getting ILIKE or ~* to use indexes....

Hi folks,

can anyone tell me or point me to the right thread.

I want my query to use indexes for company name searches but its not happening unless
is use '=' which does not server the purpose.

eg

tradein_clients=# explain SELECT co_name FROM unified_data where co_name ilike '%rajesh%' ;
NOTICE: QUERY PLAN:
Seq Scan on unified_data (cost=0.00..19293.00 rows=1 width=25)
EXPLAIN
tradein_clients=# explain SELECT co_name FROM unified_data where co_name = 'rajesh' ;
NOTICE: QUERY PLAN:
Index Scan using unified_data_co_name_key on unified_data (cost=0.00..6.26 rows=1 width=25)
EXPLAIN
tradein_clients=#

Regards
mallah.
