Whats the most efficient way to search for a sub string in SQLite?

I'm looking at the LIKE operator.

Do I have the right idea? Has this worked well for you?

Thank You.

Years have passed since the question was asked and answered and in 2012 SQLite version 3.7.15 introduced a function instr( string, substring) - returns the location of a substring in a string, 0 if not found. (https://www.techonthenet.com/sqlite/functions/instr.php)

sqlite> SELECT instr('TechOnTheNet.com', 'T');
Result: 1

I have not benchmarked against LIKE, but IMHO could be faster.
