WL#828: Combined BTREE/FULLTEXT indexes
Status: Un-Assigned — Priority: Medium
It is rather typical to have queries like "Where group_id=5 and match(name) against ("search")" can't be executed very efficiently as MySQL has to use ether index on group_id or full-text index, but not both, while selectivity of each of them could be not enough for optimal performance. We shall add possibility to add combined indexes which Feature BTREE (or possibly RTREE) functionality allowing to perform full-text search on items selected by these indexes. This is very useful for all "catalog" type applications which usually allow limit search on current group as well as some other restrictions.
