hello, i want to start a search engine i ready many articles i understood auto crawler is the best code to use that meta search which is better auto crawler or meta search no problem with server i have very good dedicated servers suggest me a good search engine script(auto crawler) budget:500$ to 1000$ thanks
I think this script can be good for you http://lucene.apache.org/nutch/ I never used it but I saw on some small search engines. It's a free so you can use your budget for some additional custom programming. In my opinion auto crawler is better because you have control over results and you don't risk to pay high license fee to big engines. However the advantage of meta is you can mix ppc feed in the results and increase your earning.
http://dataparksearch.org by far the best opensource webcrawler. Alot of humongous websites use it and im talking monstrous.
Its an old post I know but its worth the bump. Lucence is the best out there in my opinion. Digg uses it, SourceForge uses it plus several other notable mentions...
