CREATE INDEX table_field_lower_idx ON table (LOWER(field));
VACUUM ANALYZE table;
SELECT * FROM table WHERE LOWER(field) = LOWER('nolan');
SELECT * FROM table WHERE field ILIKE 'nolan%';
ILIKE is case insensitive LIKE.

This is likely an FAQ for new MySQL users at this point, or should be
if it's not.
If you are still having performance problems with the above solutions,
please send an EXPLAIN ANALYZE to the performance@ list so we can
figure out what's going on. -sc
