Hello! I'd like to have Filters reduce the search space of a Lucene Query. My experiments with DefaultSimilarity and different kind of filtering show that this does not happens. Specifically, I noticed that while calculating tf*idf the values that contribute to the idf (numDocs and docFreq) do not change even in the presence of filters.
Are parameters like numDocs and docFreq calculated at index creation or are those retrieved before applying the filter? Is there a way to have the query being executed after the filter and with values that reflect the reduced search space? SO question here: http://stackoverflow.com/questions/19882257/java-lucene-filters-seem-not-to-alter-the-query-search-space-as-expected-by-me Gist shportcut here: https://gist.github.com/gevorghari/7438048 Thanks a lot!
