: I'm still a little worried about doing uneccesarry work - this is totally : different from what I know when working with DBMS.
What are you describing as "uneccesarry work" examining every document even though you only care about the first 10, or re-executing the search when you want results 11-20 ? In the first case: there is no uneccessary work. Lucene must look at every matching docId in order to determing which docs should be the first 10. In the second case: if you feel you have a need to cache the results of a search so that fetching page#2 can be fast that's entirely your call -- but the mantra of performance optimizations is don't do it untill you need to. Typically questions about caching and performance can only be answered once you have some detailed performance numbers about your specific use cases (which requires documenting exactly what your specific use cases are, and then testing them) ... otherwise you're just guessing and your "optimizations" could very well make things worse. -Hoss --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
