Uwe Schindler commented on LUCENE-1603: --------------------------------------- An idea how to achive this, would be to make the *Filter counterparts subclasses of a new superclass MutiTermFilter, that just passes all methods to the corresponding query. This would make the filter classes simplier and one must only add the new methods to this superclass not to every filter class manually. Should I add a patch? > Changes for TrieRange in FilteredTermEnum and MultiTermQuery improvement > ------------------------------------------------------------------------ > > Key: LUCENE-1603 > URL: https://issues.apache.org/jira/browse/LUCENE-1603 > Project: Lucene - Java > Issue Type: Improvement > Affects Versions: 2.4, 2.9 > Reporter: Uwe Schindler > Assignee: Michael McCandless > Fix For: 2.9 > > Attachments: LUCENE-1603.patch, LUCENE-1603.patch > > > This is a patch, that is needed for the MultiTermQuery-rewrite of TrieRange > (LUCENE-1602): > - Make the private members protected, to have access to them from the very > special TrieRangeTermEnum > - Fix a small inconsistency (docFreq() now only returns a value, if a valid > term is existing) > - Improvement of MultiTermFilter.getDocIdSet to return > DocIdSet.EMPTY_DOCIDSET, if the TermEnum is empty (less memory usage) and > faster. > - Add the getLastNumberOfTerms() to MultiTermQuery for statistics on > different multi term queries and how may terms they affect, using this new > functionality, the improvement of TrieRange can be shown (extract from test > case there, 10000 docs index, long values): > {code} > [junit] Average number of terms during random search on 'field8': > [junit] Trie query: 244.2 > [junit] Classical query: 3136.94 > [junit] Average number of terms during random search on 'field4': > [junit] Trie query: 38.3 > [junit] Classical query: 3018.68 > [junit] Average number of terms during random search on 'field2': > [junit] Trie query: 18.04 > [junit] Classical query: 3539.42 > {code} > All core tests pass. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: java-dev-unsubscr...@lucene.apache.org For additional commands, e-mail: java-dev-h...@lucene.apache.org
