---+ 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. %TOC% ---++ ObjectMethod *hoist* <tt>($query) -> @res</tt> 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.
