Multiple keyword search: intersection instead of union — at Initial Version
|Reported by:||scribu||Owned by:|
When you search for more than one word, the SQL LIKEs are ORed together.
They should be ANDed together, so that the more words you add, the fewer, and more relevant, results you get.
Alternatively, all previous results could be returned, but ordered by relevance: more matching keyword = higher ranking. See #7394
