Hope the following problem is related enough to interfaces ...
I'm looking for the most efficient way to look through a PGSQL database
with a case insensitive search.
I tried the following queries :
1. select * from mybase where myattr like 'word%';
2. select * from mybase where myattr ~* '^word';
The first one is case-sensitive. The second one matches my needs but is
about 5 or 6 times slower than the first one.
Before I start to convert the whole database in either lowercase or
uppercase, is there a way to fasten up case insensitive searches for
words a the begining of a column or even in the middle of a row ?
Thanks a lot in advance for your help.
