> With the Queries module now filled with the FunctionQuery stuff, we should
> look at closing down contrib/queries. While not a huge contrib, it contains
> a number of pretty useful classes and some that should go elsewhere.
> Heres my proposed plan:
> - similar.* -> suggest module
> - regex.* -> queries module
> - BooleanFilter -> queries module under .filters package
> - BoostingQuery -> queries module
> - ChainedFilter -> queries module under .filters package
> - DuplicateFilter -> queries module under .filters package
> - FieldCacheRewriteMethod -> This doesn't belong in this contrib or the
> queries module. I think we should push it to contrib/misc for the time
> being. It seems to have quite a few constraints on when its useful. If
> indeed CONSTANT_SCORE_AUTO rewrite is better, then I dont see a purpose for
> it.
> - FilterClause -> class inside BooleanFilter
> - FuzzyLikeThisQuery -> suggest module. This class seems a mess with its
> Similarity hardcoded. With all that said, it does seem to do what it claims
> and with some cleanup, it could be good.
> - TermsFilter -> queries module under .filters package
> - SlowCollated* -> They can stay in the module till we have a better place to
> nuke them.
> One of the implications of the above moves, is that the xml-query-parser,
> which supports many of the queries, will need to have a dependency on the
> queries module. But that seems unavoidable at this stage.
