I enabled the extension `pg_trgm`.
I thought to query like:
SELECT
"videos".*
FROM
"videos"
WHERE
(
array_to_string(tags, ', ') ilike '%web shorts%'
)
AND EXISTS
(
SELECT
FROM
unnest(tags) AS u(val)
WHERE
u.val ILIKE '%web shorts%'

Hi,
I do have a videos table, and it has a column called `tags` of type array.
I would like to select all videos where any string inside tag column

Hi,
I do have a videos table, and it has a column called `tags` of type array. I
would like to select all videos where any string inside tag column matches a
given substring. What method should I use? The *Contains `@>` operator* will do
full string comparisons as far as I understood.
