Limit number of search results
Hello, I am looking for a way to limit the number of search results I retrieve when searching. I am only interested in (let's say) the first ten hits of a query.. maybe I want to look at hits ten..twenty to, but usually only the first results are important. Right now lucene searches through the entire index, returning way more than the desired ten documents. Any way to limit this?

Re: Limit number of search results
Hello Miles, thanks for your answer. I guess the recommended way to implement paging of results is to do your own query-results caching, right? Or does lucene also do this for me?

Re: Limit number of search results
Hello, this really doesn't answer my question ;) I've indeed read the FAQ (though I couldn't believe this point ;) . Is it recommended to do the search again - discarding the uninteresting values - because lucene caches the results, or just because lucene is so damn fast?

Re: Limit number of search results
Hello Daniel, thank you for your answer. I'm still a little worried about doing uneccesarry work - this is totally different from what I know when working with DBMS.

Haven't thought of that :) 'Bout the second thing: You're right too.. I can indeed do other optimimations which will work just fine ! Thanks for all your help!
