Re: [GENERAL] RUM-index and support for storing BIGINT as part of a tsvector+timestamp - Mailing list pgsql-general

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.
