Uwe Schindler commented on LUCENE-4580: --------------------------------------- In my opinion, for Lucene 4.x we should move the TermsFilter to core. This filter is very often used and we already have a good Automaton-based variant (DahizukMihov) filter that performs very well on lots of terms! On the other hand: TermsFilter is a Disjunction, but for drill downs you generally need Conjunctions? > Facet DrillDown should return a Filter not Query > ------------------------------------------------ > > Key: LUCENE-4580 > URL: https://issues.apache.org/jira/browse/LUCENE-4580 > Project: Lucene - Core > Issue Type: Improvement > Components: modules/facet > Reporter: Shai Erera > Priority: Minor > > DrillDown is a helper class which the user can use to convert a facet value > that a user selected into a Query for performing drill-down or narrowing the > results. The API has several static methods that create e.g. a Term or Query. > Rather than creating a Query, it would make more sense to create a Filter I > think. In most cases, the clicked facets should not affect the scoring of > documents. Anyway, even if it turns out that it must return a Query (which I > doubt), we should at least modify the impl to return a ConstantScoreQuery. -- This message is automatically generated by JIRA.
