Hi PostgresPro-guys.
I've asked this before but didn't get any response, so I'll try again. I know you have a lot on you plate...
On RUM's TODO-list is this:
- Allow multiple additional information (lexemes positions + timestamp).
- Add support for arrays.
Will any of these items support storing BIGINT as part of a tsvector+timestamp in the same index?
so one an have an index like this:
create index rum_idx on message using rum (fts_all some_opclass, folder_id, received_timestamp) WITH (attach=received_timestamp, "to"=fts_all, order_by_attach=t);
Making it possible for a query like this to use one index effectively:
WHERE fts_all @@ to_tsquery('simple', 'andre:*&jose:*') AND folder_id = ANY(ARRAY[2,3]::BIGINT[]) ORDER BY received_timestamp DESC LIMIT 10;
The reason I ask is that storing only tsvector+timestamp often is't enough because often there is some other dimention which is *very* relevant to limit the results (like what folder, or account, to search for email-messages in, instead of searching for all in the system).
Thanks.
