---|
4 | |
---|
5 | 1. NUTCH-474 - Fetcher2 crawlDelay and blocking fix (Dogacan Guney via ab) |
---|
6 | |
---|
7 | 2. NUTCH-443 - Allow parsers to return multiple Parse objects. |
---|
8 | (Dogacan Guney et al, via ab) |
---|
9 | |
---|
10 | 3. NUTCH-393 - Indexer should handle null documents returned by filters. |
---|
11 | (Eelco Lempsink via ab) |
---|
12 | |
---|
13 | 4. NUTCH-456 - Parse msexcel plugin speedup (Heiko Dietze via siren) |
---|
14 | |
---|
15 | 5. NUTCH-446 - RobotRulesParser should ignore Crawl-delay values of other |
---|
16 | bots in robots.txt (Dogacan Guney via siren) |
---|
17 | |
---|
18 | 6. NUTCH-482 - Remove redundant plugin lib-log4j (siren) |
---|
19 | |
---|
20 | 7. NUTCH-483 - Remove redundant commons-logging jar from ontology plugin |
---|
21 | (siren) |
---|
22 | |
---|
23 | 8. NUTCH-161 - Change Plain text parser to |
---|
24 | use parser.character.encoding.default property for fall back encoding |
---|
25 | (KuroSaka TeruHiko, siren) |
---|
26 | |
---|
27 | 9. NUTCH-61 - Support for adaptive re-fetch interval and detection of |
---|
28 | unmodified content. (ab) |
---|
29 | |
---|
30 | 10. NUTCH-392 - OutputFormat implementations should pass on Progressable. |
---|
31 | (cutting via ab) |
---|
32 | |
---|
33 | 11. NUTCH-495 - Unnecessary delays in Fetcher2 (dogacan) |
---|
34 | |
---|
35 | 12. NUTCH-443 - allow parsers to return multiple Parse object, this will speed |
---|
36 | up the rss parser (dogacan via mattmann). This update is a fix and semantics |
---|
37 | change from the original patch for NUTCH-443. The original patch did not tell |
---|
38 | the Indexer to read crawl_parse too so that it can pickup sub-urls' fetch |
---|
39 | datums. This patch addresses that issue. Now, if Fetcher gets a null content, |
---|
40 | instead of pushing an empty content, it filters the null content. |
---|
41 | |
---|
42 | 13. NUTCH-485 - Change HtmlParseFilter 's to return ParseResult object instead of |
---|
43 | Parse object. (Gal Nitzan via dogacan) |

---|
46 | some query parameters. (Emmanuel Joke via dogacan) |

---|
49 | (Ilya Vishnevsky via dogacan) |
---|
50 | |
---|
51 | 16. NUTCH-444 Possibly use a different library to parse RSS feed for improved |
---|
52 | performance and compatibility. This patch introduced a new plugin, feed, |
---|
53 | that includes an index filter and a parse plugin for feeds that uses ROME. |
---|
54 | There was discussion to remove parse-rss, in light of the feed plugin, |
---|
55 | however, this patch does not explicitly remove parse-rss. (dogacan, mattmann) |
---|
56 | |
---|
57 | 17. NUTCH-471 - Fix synchronization in NutchBean creation. |

725 | 59. NUTCH-298 - If a 404 for a robots.txt is returned a NPE is thrown |
---|
726 | (Stefan Groschupf via jerome) |
---|
727 | |
---|
728 | 60. NUTCH-275 - Fetcher not parsing XHTML-pages at all (jerome) |
---|
729 | |
---|
730 | 61. NUTCH-301 - CommonGrams loads analysis.common.terms.file for each query |

731 | (Stefan Groschupf via jerome) |
---|
732 | |
---|
733 | 62. NUTCH-110 - OpenSearchServlet outputs illegal xml characters |
---|
734 | (stack@archive.org via siren) |
---|
735 | |
---|
736 | 63. NUTCH-292 - OpenSearchServlet: OutOfMemoryError: Java heap space |
---|
737 | (Stefan Neufeind via siren) |

739 | 64. NUTCH-307 - Wrong configured log4j.properties (jerome) |
---|
740 | |
---|
741 | 65. NUTCH-303 - Logging improvements (jerome) |
---|
742 | |
---|
743 | 66. NUTCH-308 - Maximum search time limit (ab) |
---|
744 | |
---|
745 | 67. NUTCH-306 - DistributedSearch.Client liveAddresses concurrency |
---|
746 | problem (Grant Glouser via siren) |
---|
747 | |
---|
748 | 68. Update to hadoop-0.4 (Milind Bhandarkar, cutting) |
---|
749 | |
---|
750 | 69. NUTCH-317 - Clarify what the queryLanguage argument of |
---|
751 | Query.parse(...) means (jerome) |
---|
752 | |
---|
753 | 70. Added alternative experimental web gui in contrib containing |
---|
754 | extensions like subcollection, keymatch, user preferences, |
---|
755 | caching, implemented mainly using tiles and jstl (siren) |
---|
756 | |
---|
757 | 71. NUTCH-320 DmozParser does not output list of urls to stdout |
---|
758 | but to a log file instead. Original functionality restored. |
---|
759 | |
---|
760 | 72. NUTCH-271 - Add ability to limit crawling to the set of initially |
---|
761 | injected hosts (db.ignore.external.links) (Philippe Eugene, |
---|
762 | Stefan Neufeind via ab) |
---|
763 | |
---|
764 | 73. NUTCH-293 - Support for Crawl-Delay (Stefan Groschupf via ab) |
---|
765 | |
---|
766 | 74. NUTCH-327 - Fixed logging directory on cygwin (siren) |
---|
767 | |
---|
768 | Release 0.7 - 2005-08-17 |
---|
769 | |
---|
770 | 1. Added support for "type:" in queries. Search results are limited/qualified |
---|
771 | by mimetype or its primary type or sub type. For example, |
---|
772 | (1) searching with "type:application/pdf" restricts results |
---|
773 | to pages which were identified to be of mimetype "application/pdf". |
---|
774 | (2) with "type:application", nutch will return pages of |
---|
775 | primary type "application". |
---|
776 | (3) with "type:pdf", only pages of sub type "pdf" will be listed. |
---|
777 | (John Xing, 20050120) |
---|
778 | |
---|
779 | 2. Added support for "date:" in queries. Last-Modified is indexed. |
---|
780 | Search results are restricted by lower and upper date (inclusive) |
---|
781 | as date:yyyymmdd-yyyymmdd. For example, date:20040101-20041231 |
---|
782 | only returns pages with Last-Modified in year 2004. |
---|
783 | (John Xing, 20050122) |
---|
784 | |
---|
785 | 3. Add URLFilter plugin interface and convert existing url filters into |
---|
786 | plugins. (John Xing, 20050206) |
---|
787 | |
---|
788 | 4. Add UpdateSegmentsFromDb tool, which updates the scores and |
---|
789 | anchors of existing segments with the current values in the web |
---|
790 | db. This is used by CrawlTool, so that pages are now only fetched |
---|
791 | once per crawl. (Doug Cutting, 20050221) |
---|
792 | |
---|
793 | 5. Moved code into org.apache.nutch sub-packages. Changed license to |
---|
794 | Apache 2.0. Removed jar files whose licenses do not permit |
---|
795 | redistribution by Apache. Disabled compilation of plugins which |
---|
796 | require these libraries. (Doug Cutting 20050301) |
---|
797 | |
---|
798 | 6. Index host and title in separate fields. Host was indexed |
---|
799 | previously only as a part of the URL. Title was indexed as an |
---|
800 | anchor. Now boosts for matching these fields may be adjusted |
---|
801 | separately from boosts for matching anchors and url. Also: move |
---|
802 | site indexing to index-basic plugin to minimize the number of |
---|
803 | times the URL needs to be parsed; and, stop using anchor analyzer |
---|
804 | for anything but anchors. (Piotr Kosiorowski via Doug Cutting |
---|
805 | 20050323) |
---|
806 | |
---|
807 | 7. Add servlet Cached.java that serves cached Content of any mime type. |
---|
808 | Slightly modified are web.xml and cached.jsp. |
---|
809 | (John Xing, 20050401) |
---|
810 | |
---|
811 | 8. Add skipCompressedByteArray() to WritableUtils.java. |
---|
812 | (John Xing, 20050402) |
---|
813 | |
---|
814 | 9. Fixes to jsp and static web pages. These now use relative links, |
---|
815 | so that the Nutch webapp file can be used in places other than at |
---|
816 | the root. Also fixed links to the about and help pages. Bug #32. |
---|
817 | (Jerome Charron via cutting, 20050404) |
---|
818 | |
---|
819 | 10. Added some features to DistributedSearch: new segments can be added |
---|
820 | to searchservers without restarting the frontend, defective search |
---|
821 | servers are not queried until tey come back online, watchdog keeps |
---|
822 | an eye for your searchservers and writes simple statistics. |
---|
823 | (Sami Siren, 20050407) |
---|
824 | |
---|
825 | 11. Fix for bug #4 - Unbalanced quote in query eats all resources. |
---|
826 | (Piotr Kosiorowski, Sami Siren, 20050407) |
---|
827 | |
---|
828 | 12. Close Issue #33 - MIME content type detector (using magic char sequences). |
---|
829 | (Jerome Charron and Hari Kodungallur via John Xing, 20050416) |
---|
830 | |
---|
831 | 13. Add a servlet that implements A9's OpenSearch RSS web service. |
---|
832 | (cutting, 20050418) |
---|
833 | |
---|
834 | 14. Remove references to link analysis from tutorial, and enable |
---|
835 | scoring by link count when generating fetchlists and searching. |
---|
836 | (cutting, 20040419) |
---|
837 | |
---|
838 | 15. Make query boosts for host, title, anchor and phrase matches |
---|
839 | configurable. (Piotr Kosiorowski via cutting, 20050419) |
---|
840 | |
---|
841 | 16. Add support for sorting search results and search-time deduping by |
---|
842 | fields other than site. |
---|
843 | |
---|
844 | 17. Automatically convert range queries into cached range filters. |
---|
845 | This improves the performance and scalability of, e.g., date range |
---|
846 | searching. |
---|
847 | |
---|
848 | 18. Several methods have been renamed due to misspellings. The old |
---|
849 | methods have been deprecated and will be removed before the 1.0 |
---|
850 | release. |
---|
851 | |
---|
852 | |
---|
853 | Release 0.6 |
---|
854 | |
---|
855 | 1. Added clustering-carrot2 plugin, together with introduction of clustering |
---|
856 | api and modification to search jsp. (Dawid Weiss via John Xing, 20040809) |
---|
857 | |
---|
858 | 2. Make a number of changes to NDFS (Nutch Distributed File System) |
---|
859 | to fix bugs, add admin tools, etc. |
---|
860 | |
---|
861 | Also, modify all command line tools so you can indicate whether to |
---|
862 | use NDFS or the local filesystem. If you indicate nothing, then |
---|
863 | it defaults to the local fs. |
---|
864 | |
---|
865 | I've used this to do a 35m page crawl via NDFS, distributed over a |
---|
866 | dozen machines. (Mike Cafarella) |
---|
867 | |
---|
868 | 3. Add support for BASE tags in HTML. Outlinks are now correctly |
---|
869 | extracted when a BASE tag is present. (cutting) |
---|
870 | |
---|
871 | 4. Fix two bugs in result pagination. When the last hit on a page |
---|
872 | was the last hit overall, the "next" button was sometimes shown |
---|
873 | when the "show all" button should be shown instead. Also, in |
---|
874 | certain cases, the "show all" button would be shown when the |
---|
875 | "next" button should have been shown. (cutting) |
---|
876 | |
---|
877 | 5. Add config parameter "indexer.max.tokens" that determines the |
---|
878 | maximum number of tokens indexed per field. (Andy Hedges via cutting) |
---|
879 | |
---|
880 | 6. Add parser for mp3 files. (Andy Hedges via cutting) |
---|
881 | |
---|
882 | 7. Add RegexUrlNormalizer. This is useful for things like stripping |
---|
883 | out session IDs from URLs. To use it, add values for |
---|
884 | urlnormalizer.class and urlnormalizer.regex.file to your |
---|
885 | nutch-site.xml. The RegexUrlNormalizer class extends the |
---|
886 | BasicUrlNormalizer, and does basic normalization as well. |
---|
887 | (Luke Baker via cutting) |
---|
888 | |
---|
889 | 8. Added Swedish translation (Stefan Verzel via Sami Siren, 20040910) |
---|
890 | |
---|
891 | 9. Added Polish translation (Andrzej Bialecki, 20040911) |
---|
892 | |
---|
893 | 10. Added 3 more language profiles to language identifier (ru,hu,pl). |
---|
894 | Other changes to language identifier: Porfiles converted to utf8, |
---|
895 | added some test cases, changed the similarity calculation. |
---|
896 | (Sami Siren, 20040925) |
---|
897 | |
---|
898 | 11. Added plugin parse-rtf (Andy Hedges via John Xing, 20040929) |
---|
899 | |
---|
900 | 12. Added plugin index-more and more.jsp (John Xing, 20041003) |
---|
901 | |
---|
902 | 13. Added "View as Plain Text" feature. A new op OP_PARSETEXT is introduced |
---|
903 | in DistributedSearch.java. text.jsp is added. (John Xing, 20041006) |
---|
904 | |
---|
905 | 14. Fixed a bug that fails cached.jsp, explain.jsp, anchors.jsp and text.jsp |
---|
906 | (but not search.jsp) with NullPointerException in distributed search. |
---|
907 | It seems that this bug appears after "hits per site" stuff is added. |
---|
908 | The fix is done in Hit.java, making sure String site is never null. |
---|
909 | Hope this fix not have bad effetct on "hits per site" code. |
---|
910 | (John Xing, 20041006) |
---|
911 | |
---|
912 | 15. Fixed a bug that fails fullyDelete() in FileUtil.java for |
---|
913 | LocalFileSystem.java. This bug also exposes possible incompleteness |
---|
914 | of NDFSFile.java, where a few methods are not supported, including |
---|
915 | delete(). Nothing changed in NDFSFile.java though. Leave it for future |
---|
916 | improvement (John Xing, 20041022). |
---|
917 | |
---|
918 | 16. Introduced option -noParsing to Fetcher.java and added ParseSegment.java. |
---|
919 | A new status code CANT_PARSE is added to FetcherOutput.java. |
---|
920 | Without option -noParsing , no change in fetcher behavior. With |
---|
921 | option -noParsing, fetcher does crawls only, no parsing is carried out. |
---|
922 | Then, ParseSegment.java should be used to parse in separate pass. |
---|
923 | (John Xing, 20041025) |
---|
924 | |
---|
925 | 17. Added ontology plugin. Currently it is used for query refinement, as |
---|
926 | examplified in refine-query-init.jsp and refine-query.jsp. By default, |
---|
927 | query refinement is disabled in search.jsp. Please check |
---|
928 | ./src/plugin/ontology/README.txt for further description. |
---|
929 | Ontology plugin certainly can be used for many other things. |
---|
930 | (Michael J. Pan via John Xing, 20041129) |
---|
931 | |
---|
932 | 18. Changed fetcher.server.delay to be a float, so that sub-second |
---|
933 | delays can be specified. (cutting) |
---|
934 | |
---|
935 | 19. Added plugin.includes config parameter that determines which |
---|
936 | plugins are included. By default now only http, html and basic |
---|
937 | indexing and search plugins are enabled, rather than all plugins. |
---|
938 | This should make default performance more predictable and reliable |
---|
939 | going forward. (cutting) |
---|
940 | |
---|
941 | 20. Cleaned up some filesystem code, including: |
---|
942 | |
---|
943 | - Replaced BufferedRandomAccessFile with two simpler utilties, |
---|
944 | NFSDataInputStream and NFSDataOutputStream. |
---|
945 | |
---|
946 | - Fixed the bug where SequenceFiles were no longer flushed when |
---|
947 | created, so that, when fetches crashed, segments were |
---|
948 | unreadable. Now segments are always readable after crashes. |
---|
949 | Only the contents of the last buffer is lost. |
---|
950 | |
---|
951 | - Simplified the FSOutputStream API to not include seek(). We |
---|
952 | should never need that functionality. |
---|
953 | |
---|
954 | - Simplified LocalFileSystem's implementations of FSInputStream |
---|
955 | and FSOutputStream and optimized FSInputStream.seek(). |
---|
956 | |
---|
957 | (cutting) |
---|
958 | |
---|
959 | 21. Fixed BasicUrlNormalizer to better handle relative urls. The file |
---|
960 | part of a URL is normalized in the following manner: |
---|
961 | |
---|
962 | 1. "/aa/../" will be replaced by "/" This is done step by step until |
---|
963 | the url doesn´t change anymore. So we ensure, that |
---|
964 | "/aa/bb/../../" will be replaced by "/", too |
---|
965 | |
---|
966 | 2. leading "/../" will be replaced by "/" |
---|
967 | |
---|
968 | (Sven Wende via cutting) |
---|
969 | |
---|
970 | 22. Fix Page constructors so that next fetch date is less likely to be |
---|
971 | misconstrued as a float. This patches a problem in WebDBInjector, |
---|
972 | where new pages were added to the db with nextScore set to the |
---|
973 | intended nextFetch date. This, in turn, confused link analysis. |
---|
974 | |
---|
975 | 23. In ndfs code, replace addLocalFile(), putToLocalFile() with |
---|
976 | copyFromLocalFile(), moveFromLocalFile(), copyToLocalFile() and |
---|
977 | moveToLocalFile(). (John Xing, 20041217) |
---|
978 | |
---|
979 | 24. Added new config parameter fetcher.threads.per.host. This is used |
---|
980 | by the Http protocol. When this is one behavior is as before. |
---|
981 | When this is greater than one then multiple threads are permitted |
---|
982 | to access a host at once. Note that fetcher.server.delay is no |
---|
983 | longer consistently observed when this is greater than one. |
---|
984 | (Luke Baker via Doug Cutting) |
---|
985 | |
---|
986 | Release 0.5 |
---|
987 | |
---|
988 | 1. Changed plugin directory to be a list of directories. |
---|
989 | |
---|
990 | 2. Permit Plugin to be the default plugin implementation. |
---|
991 | |
---|
992 | 3. Added pluggable interface for network protocols in new package |
---|
993 | net.nutch.protocol. Moved http code from core into a plugin. |
---|
994 | |
---|
995 | 4. Added pluggable interface for content parsing in new package |
---|
996 | net.nutch.parse. Moved html parsing code from core into a |
---|
997 | plugin. |
---|
998 | |
---|
999 | 5. Fixed a bug in NutchAnalysis where 16-bit characters were not |
---|
1000 | processed correctly. |
---|
1001 | |
---|
1002 | 6. Fixed bug #971731: random summaries on result page. |
---|
1003 | (Daniel Naber via cutting) |
---|
1004 | |
---|
1005 | 7. Made Nutch logo transparent. (Daniel Naber via cutting) |
---|
1006 | |
---|
1007 | 8. Added file protocol plugin. (John Xing via cutting) |
---|
1008 | |
---|
1009 | 9. Added ftp protocol plugin. (John Xing via cutting) |
---|
1010 | |
---|
1011 | 10. Added pdf and msword parser plugins. (John Xing via cutting) |
---|
1012 | |
---|
1013 | 11. Added pluggable indexing interface. By default, url, content, |
---|
1014 | anchors and title are indexed, as before, but now one can easily |
---|
1015 | alter this to, e.g., index metadata. A demonstration is provided |
---|
1016 | which extracts and indexes Creative Commons license urls. (cutting) |
---|
1017 | |
---|
1018 | 12. Add language identification plugin. |
---|
1019 | |
---|
1020 | The process of identification is as follows: |
---|
1021 | |
---|
1022 | 1. html (html only, HTML 4.0 "lang" attribute) |
---|
1023 | 2. meta tags (html only, http-equiv, dc.language) |
---|
1024 | 3. http header (Content-Language) |
---|
1025 | 4. if all above fail "statistical analysis" |
---|
1026 | |
---|
1027 | 1 & 2 are run during the fetching phase and 3 & 4 are run on |
---|
1028 | indexing phase. |
---|
1029 | |
---|
1030 | Currently supported languages (in "statistical analysis") are |
---|
1031 | da,de,el,en,es,fi,fr,it,nl,sv and pt. The corpus used was grabbed |
---|
1032 | from http://www.isi.edu/~koehn/europarl/ and the profiles were |
---|
1033 | build with tool supplied in patch. |
---|
1034 | |
---|
1035 | After indexing the language can be found from field named "lang" |
---|
1036 | |
---|
1037 | It's not 100% accurate but it's a start. |
---|
1038 | (Sami Siren) |
---|
1039 | |
---|
1040 | 13. Added SegmentMergeTool and "mergesegs" command, to remove |
---|
1041 | duplicated or otherwise not used content from several segments and |
---|
1042 | joining them together into a single new segment. The tool also |
---|
1043 | optionally performs several other steps required for proper |
---|
1044 | operation of Nutch - such as indexing segments, deleting |
---|
1045 | duplicates, merging indices, and indexing the new single segment. |
---|
1046 | (Andrzej Bialecki) |
---|
1047 | |
---|
1048 | 14. Add the ability to retrieve ParseData of a search hit. ParseData |
---|
1049 | contains many valuable properties of a search hit. |
---|
1050 | |
---|
1051 | This is required (among others) to properly display the cached |
---|
1052 | content because it's not possible to determine the character |
---|
1053 | encoding from the output of the getContent() method (which returns |
---|
1054 | byte[]). The symptoms are that for HTML pages using non-latin1 or |
---|
1055 | non-UTF8 encodings the cached preview will almost certainly look |
---|
1056 | broken. Using the attached patch it is possible to determine the |
---|
1057 | character encoding from the ParseData (for HTTP: Content-Type |
---|
1058 | metadata), and encode the content accordingly. (Andrzej Bialecki) |
---|
1059 | |
---|
1060 | 15. Add a pluggable query interface. By default, the content, anchor |
---|
1061 | and url fields are searched as before. A sample plugin indexes |
---|
1062 | the host name and adds a "site:" keyword to query parsing. |
---|
1063 | |
---|
1064 | 16. Added support for "lang:" in queries. For example, searching with |
---|
1065 | "lang:en" restricts results to pages which were identified to |
---|
1066 | be in English. |
---|
1067 | |
---|
1068 | 17. Automatically optimize field queries to use cached Lucene filters. |
---|
1069 | This makes, for example, searches restricted by languages or sites |
---|
1070 | that are very common much faster. |
---|
1071 | |
---|
1072 | 18. Improved charset handling in jsp pages. (jshin by cutting) |
---|
1073 | |
---|
1074 | 19. Permit topic filtering when injecting DMOZ pages. (jshin by cutting) |
---|
1075 | |
---|
1076 | 20. When parsing crawled pages, interpret charset specifications in |
---|
1077 | html meta tags. (jshin by cutting) |
---|
1078 | |
---|
1079 | 21. Added support for "cc:licensed" in queries, which searches for documents |
---|
1080 | released under Creative Commons licenses. Attributes of the |
---|
1081 | license may also be queried, with, e.g., "cc:by" for |
---|
1082 | attribution-required licenses, "cc:nc" for non-commercial |
---|
1083 | licenses, etc. |
---|
1084 | |
---|
1085 | 22. Relative paths named in plugin.folders are now searched for on the |
---|
1086 | classpath. This makes, e.g., deployment in a war file much simpler. |
---|
1087 | |
---|
1088 | 23. Modifications to Fetcher.java. |
---|
1089 | |
---|
1090 | 1. Make sure it works properly with regard to creation and initialization |
---|
1091 | of plugin instances. The problem was that multiple threads race to |
---|
1092 | startUp() or shutDown() plugin instances. It was solved by synchronizing |
---|
1093 | certain codes in PluginRepository.java and Extension.java. |
---|
1094 | (Stefan Groschupf via John Xing) |
---|
1095 | |
---|
1096 | 2. Added code to explictly shutDown() plugins. Otherwise FetcherThreads |
---|
1097 | may never return (quit) if there are still data or other structures |
---|
1098 | (e.g., persistent socket connections) associated with plugins. (John Xing) |
---|
1099 | |
---|
1100 | 3. Fixed one type of Fetcher "hang" problems by monitoring named |
---|
1101 | FetcherThreads. If all FetcherThreads are gone (finished), |
---|
1102 | Fetcher.java is considered done. The problem was: there could be |
---|
1103 | runaway threads started by external libs via FetcherThreads. |
---|
1104 | Those threads never return, thus keep Fetcher from exiting normally. |
---|
1105 | (John Xing) |
---|
1106 | |
---|
1107 | 24. Eliminate excessive hits from sites. This is done efficiently by |
---|
1108 | adding the site name to Hit instances, and, when needed, |
---|
1109 | re-querying with too-frequent sites prohibited in the query. |
---|
1110 | |
---|
1111 | |
---|
1112 | Release 0.4 |

---|
1133 | 10. Added Thai translation. (Pichai Ongvasith via Doug Cutting) |
---|
1134 | |
---|
1135 | 11. Added Robots.txt & throttling support to Fetcher.java. (Mike |
---|
1136 | Cafarella) |
---|
1137 | |
---|
1138 | 12. Added nightly build. (Doug Cutting) |
---|
1139 | |

1140 | 13. Default all link scores to 1.0. (Doug Cutting) |
---|
1141 | |
---|
1142 | 14. Permit one to keep internal links. (Doug Cutting) |
---|
1143 | |
---|
1144 | 15. Fixed dedup to select shortest URL. (Doug Cutting) |
---|
1145 | |
---|
1146 | 16. Changed index merger so that merged index is written to named |
---|
1147 | directory, rather than to a generated name in that directory. |
---|
1148 | (Doug Cutting) |
---|
1149 | |
---|
1150 | 17. Disable coordination weighting of query clauses and other minor |
---|
1151 | scoring improvements. (Doug Cutting) |
---|
1152 | |
---|
1153 | 18. Added a new command, crawl, that constructs a database, injects a |
---|
1154 | url file and performs a few rounds of generate/fetch/updatedb. |
---|
1155 | This simplifies use for intranet sites. Changed some defaults to |
---|
1156 | be more intranet friendly. (Doug Cutting) |
---|
1157 | |
---|
1158 | 19. Fixed a bug where Fetcher.java didn't construct correct relative |
---|
1159 | links when a page was redirected. (Doug Cutting) |
---|
1160 | |
---|
1161 | 20. Fixed a query parser problem with lookahead over plusses and minuses. |
---|

---|
1167 | (Sami Siren via Doug Cutting) |
---|
1168 | |
---|
1169 | 23. Fix a bug when throttling is disabled. (Sami Siren via Doug Cutting) |
---|
