--- Comment #14 from David Cook <dc...@prosentient.com.au> --- More thoughts on C4::Search::buildQuery and Koha::QueryParser... C4::Search::buildQuery: PRO: Right/left/right&&left truncation, QueryFuzzy appears to work, QueryWeightFields works (except when QueryAutoTruncate is on), QueryStemming works with wordlists. CON: No support for phrases, lots of ugly spaghetti code which is mutually exclusive, incorrectly defines variables, etc. FUTURE: Planning to integrate "QueryWeightFields", "QueryFuzzy", "QueryAutoTruncate", and "QueryStemming" into _build_initial_query(). "QueryWeightFields" and "QueryFuzzy" could be improved. "QueryStemming" is a tough one...as it really is only useful for Word Lists...so we'll have to check the structure and make sure there are no quotation marks sneaking in as they'll cause problems. That should work all right. -- Koha::QueryParser: PRO: Automatically detects phrases, automatically detects right truncation. "Koha::QueryParser::Driver::PQF::query_plan::node" already uses "QueryAutoTruncate", some "QueryWeightFields"-like functionality (which needs a more configuration and possibly some code tweaks). CON: No left truncation, no left && right truncation, no easy way to designate a phrase (except by wrapping in quotes or by providing an alias) FUTURE: "Koha::QueryParser::Driver::PQF::query_plan::node" could make it easy to add "QueryStemming" and "QueryFuzzy". We could also add support for left truncation and left && right truncation using that same module. Improve relevance bumps (aka QueryWeightFields functionality) in queryparser.yaml. -- You are receiving this mail because: You are watching all bug changes. _______________________________________________ Koha-bugs mailing list Koha-bugs@lists.koha-community.org http://lists.koha-community.org/cgi-bin/mailman/listinfo/koha-bugs website : http://www.koha-community.org/ git : http://git.koha-community.org/ bugs : http://bugs.koha-community.org/
