Package TWiki::Query::HoistREs

Static functions to extract regular expressions from queries. The REs can be used in caching stores that use the TWiki standard inline meta-data representation to pre-filter topic lists for more efficient query matching.

See Store/RcsFile.pm for an example of usage.

ObjectMethod hoist ($query) -> @res

Extract useful filter REs from the given query. The list returned is a list of filter expressions that can be used with a cache search to refine the list of topics. The full query should still be applied to topics that remain after the filter match has been applied; this is purely an optimisation.
