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 = 5
The 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
