I've got the following query:

SELECT COUNT(DISTINCT j0_.id) AS sclr0FROM ja_customers j0_WHERE
((LOWER(j0_.name_first) LIKE '%asd%'
OR LOWER(j0_.name_last) LIKE '%asd%'
OR LOWER(j0_.company) LIKE '%asd%'
OR LOWER(j0_.phone) LIKE '%asd%'
OR LOWER(j0_.mobile) LIKE '%asd%')
AND j0_.deleted = 'f'
AND j0_.clientid = 2565)
AND j0_.clientid = 2565

It returns: 3

I created a GIN index;

CREATE INDEX CONCURRENTLY ON public.ja_customers USING gin (name_first
gin_trgm_ops, name_last gin_trgm_ops, company gin_trgm_ops, phone
gin_trgm_ops, mobile gin_trgm_ops);

New query to hit the new index:

SELECT COUNT(DISTINCT j0_.id) AS sclr0FROM ja_customers j0_WHERE
j0_.name_first LIKE '%asd%'
OR j0_.name_last LIKE '%asd%'
OR j0_.company LIKE '%asd%'
OR j0_.phone LIKE '%asd%'
OR j0_.mobile LIKE '%asd%'
AND j0_.deleted = 'f'
AND j0_.clientid = 2565
AND j0_.clientid = 2565

It returns: 532

The problem is that the new query returns different results...

Please, what am I missing guys?

Cheers
