So, I want to SELECT all docids, which dates in range:
SELECT attrs FROM document_resinfo WHERE attrs @? '$.dates[*].datetime() ? (@ >= "2020-10-02".datetime())';
How can I create index on attrs field to query docids with other date? Thanks.
Have you tried just putting a default index on that column? I think it should work fine.
CREATE INDEX attrs_idx ON test (attrs)
IIRC, jsonb can be indexed like any other column and you get significant performance benefits when using the index. Also IIRC, you can index "deeper" into jsonb if you only want to index part of the jsonb structure - which is more efficient, so you don't index a bunch of elements that you never search.
Have you tried this approach? What problems are you experiencing?
