Multiple indexes matched with OR

This example uses the following table and indexes:

CREATE TABLE IF NOT EXISTS cycling.comments_vs (
  record_id timeuuid,
  id uuid,
  commenter text,
  comment text,
  comment_vector VECTOR <FLOAT, 5>,
  created_at timestamp,
  PRIMARY KEY (id, created_at)
CREATE CUSTOM INDEX commenter_idx 
    ON cycling.comments_vs (commenter) 
    USING 'StorageAttachedIndex';
CREATE CUSTOM INDEX created_at_idx 
    ON cycling.comments_vs (created_at) 
    USING 'StorageAttachedIndex';
    ON cycling.comments_vs (comment_vector) 
    USING 'StorageAttachedIndex';

Several indexes are created for the table to demonstrate how to query for matches on more than one column.

Query for a match on either one column or the other:

  • Query

  • Result

SELECT * FROM cycling.comments_vs 
        created_at='2017-03-21 21:11:09.999000+0000' 
        OR created_at='2017-03-22 01:16:59.001000+0000';
 id                                   | created_at                      | comment                           | comment_vector               | commenter | record_id
