: I am looking a bit at the source code and there's something that's : puzzling me. It looks like filtering a query reexecutes it, but this : time applying the filter. Not applying the filter to some results : stored with the query. : If this is true, I fail to see the point of having filters, instead : of just building a bigger query.
the main advantage is that Filter's don't affect the scores of the Query itself. A secondary advantage is that a Filter can be cached, so that the computation necceessary for complex Filter can be done only once -- that wouldn't be possible with most Query types. (there are also some changes in the works that will allow a Searcher to look at what is matched by the Filter and skip scoring matches to the Query that the Filter will weed out -- but this is just a hypothetical benefit that doesn't exist yet) : : Thanks : : --------------------------------------------------------------------- : To unsubscribe, e-mail: [EMAIL PROTECTED] : For additional commands, e-mail: [EMAIL PROTECTED] : -Hoss --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
