22 Koha::SearchEngine::Zebra::QueryBuilder - Zebra query objects from user-supplied queries
23 Several methods are pass-throughs to C4 methods or other methods here
27 This provides the functions that take a user-supplied search query, and
28 provides something that can be given to Zebra to get answers.
