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)
)
WITH CLUSTERING ORDER BY (created_at DESC);
CREATE CUSTOM INDEX commenter_idx ON cycling.comments_vs (commenter)
USING 'StorageAttachedIndex'
WITH OPTIONS = {'case_sensitive': 'true', 'normalize': 'true', 'ascii': 'true'};
CREATE CUSTOM INDEX created_at_idx ON cycling.comments_vs (created_at)
USING 'StorageAttachedIndex';
CREATE CUSTOM INDEX comment_ann_idx 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:
SELECT * FROM cycling.comments_vs
WHERE created_at='2017-03-21 21:11:09.999'
OR created_at='2017-03-22 01:16:59.001';Results
id | created_at | comment | comment_vector | commenter | record_id
