Hi there,I've got the following query:
SELECT COUNT(DISTINCT j0_.id) AS sclr10
FROM customers j0_
WHERE ((LOWER(j0_.name_first) LIKE '%some%'
OR LOWER(j0_.name_last) LIKE '%some%')
AND j0_.id = 5)
AND j0_.id = 5The query is taking ages to run.I read about wildcards and it seems I have to use a function with to_tsvector ?
CREATE INDEX CONCURRENTLY ON public.customers USING gin ("clientid", ("full_text_universal_cast"("name_first"::"text")), ("full_text_universal_cast"("name_last"::"text")));full_text_universal_cast:CREATE OR REPLACE FUNCTION public.full_text_universal_cast(doc_data "text")
RETURNS "tsvector" AS
$BODY$
SELECT to_tsvector('english', COALESCE(TRIM(CAST(doc_data AS TEXT)), ''));
$BODY$
LANGUAGE sql IMMUTABLE
COST 1000;Would be something like above? Because it's not working...What am I missing guys?Thanks
Maybe Lucas Possamai can help. He seems to be a little bit further along in this exercise.
I'm too tired to care at the moment. And I haven't had much practical work here anyway.
