< li > Simple caching for filters< / li >

< li > "Like this" queries< / li >
< li > Boolean, Term, and UserInput (parsed with existing query parser)< / li >
< li > BoostingQuery - a class that can downgrade scores for hits on
certain terms rather than the hard-line approach taken by BooleanClause.Occurs.MUST_NOT< / li >
2007-10-09 17:45:27 -04:00
< li > FilteredQuery, RangeFilter, DuplicateFilter and "TermsFilter" for non-sequential terms< / li >

< li > "FuzzyLikeThis" a new query which is a cross between "LikeThis" and "fuzzy" but with
better scoring of fuzzy terms than standard fuzzy queries< / li >
< li > A modular design with expandable support for new query/filter types< / li >
< / ul >
< / p >
< p > This code is dependent on the "queries" contrib module although the "CoreParser" can be compiled with just Lucene core if required< / p >
