| 143 | <p>Het doorzoeken van het web vormt een basiseis voor het surfen over het internet. Toch vermindert |
|---|
| 144 | het aantal zoekmachines. De huidige markt met enkele aanbieders kent binnenkort wellicht nog maar |
|---|
| 145 | één enkele aanbieder. Die ene onderneming krijgt dan de macht over bijna alle zoekopdrachten en |
|---|
| 146 | kan deze gebruiken voor haar commerciële doeleinden. Dat zou niet goed zijn voor de internetgebruikers. |

| 151 | <p>Nutch biedt een transparant alternatief voor de commerciële webzoekmachines. |
|---|
| 152 | Alleen bij open-source-zoekresultaten valt er volledig op te vertrouwen dat zij zonder dubieuze |
|---|
| 153 | filters zijn geselecteerd (of is hun filtering tenminste voor iedereen zichtbaar). |
|---|
| 154 | Alle huidige belangrijke zoekmachines hanteren eigen formules |
|---|
| 155 | voor de rangorde van treffers en leggen niet uit hoe een bepaalde pagina aan zijn plaats in de lijst van |
|---|
| 156 | treffers komt. |
|---|
| 157 | Bovendien bepalen sommige zoekmachines hun indexering op basis van betalingen in plaats van |
|---|
| 158 | op de verdiensten van de sites zelf. |
|---|
| 159 | Nutch, daarentegen, heeft niets te verbergen en heeft geen reden om |
|---|
| 160 | zijn zoekresultaten of zijn crawler op welke manier dan ook te beïnvloeden, |
|---|
| 161 | behalve dan door elke gebruiker het best mogelijke resultaat te willen bieden. |
