Uwe Schindler commented on LUCENE-4410: --------------------------------------- It is not biggish :-) It is same code as before :-) I don't care, but the RA autodetection was always horrible to me, now its hidden behind something else! > Make FilteredQuery more flexible with regards to how filters are applied > ------------------------------------------------------------------------ > > Key: LUCENE-4410 > URL: https://issues.apache.org/jira/browse/LUCENE-4410 > Project: Lucene - Core > Issue Type: Improvement > Components: core/search > Affects Versions: 4.0-BETA > Reporter: Simon Willnauer > Fix For: 5.0, 4.0 > > Attachments: LUCENE-4410.patch, LUCENE-4410.patch, LUCENE-4410.patch > > > Currently FilteredQuery uses either the "old" lucene 3 leap frog approach or > pushes the filter down together with accepted docs. Yet there might be more > strategies required to fit common usecases like geo-filtering where a rather > costly function is applied to each document. Using leap frog this might > result in a very slow query if the filter is advanced since it might have > linear running time to find the next valid document. We should be more > flexible with regards to those usecases and make it possible to either tell > FQ what to do or plug in a strategy that applied a filter in a different way. > The current FQ impl also uses an heuristic to decide if RA or LeapFrog should > be used. This is really an implementation detail of the strategy and not of > FQ and should be moved out. -- This message is automatically generated by JIRA.
