* There isn't phrase search with GIN index. This problem relates with previous problem. It is need position information to perform phrase search. RUM being an extention, and having index-access-methods as extentions is new in 9.6, where phrase-search was introduced, this isn't really true, or am I missing something? RUM is very good for phrase search, since it has access to coordinates in index, check slides from PGconf.eu ( http://www.sai.msu.su/~megera/postgres/talks/pgconfeu-fts-2016.pdf <http://www.sai.msu.su/~megera/postgres/talks/pgconfeu-fts-2016.pdf>). Where did you find the citation ? https://github.com/postgrespro/rum#user-content-introduction I assume I read the item wrong tho. As it's phrased, it (for me at least but I'm Norwegian) seems like phrase-search is not possible with GIN, which it definitely is. So I assume the real issue, that this item is trying to point out, is that phrase-search isn't reallyoptimized with GIN, just syntactic sugar. And with RUM it is optimized, not just syntactic sugar. Am I correct assuming this? -- Andreas Joseph Krogh CTO / Partner - Visena AS Mobile: +47 909 56 963 andr...@visena.com <mailto:andr...@visena.com> www.visena.com <https://www.visena.com> <https://www.visena.com>
