Indexing for BINARY LIKE operations in MySQL

Question

I know that varchar_pattern_ops exists in Postgresql for fast, index-based searches in a LIKE query, but is there any similar functionality for MySQL?<

Answer 1

Do the fact that MySQL indexes the left side of a string.

Then a string column can use the index if the query use wildcard right side :

 SELECT * FROM your_table WHERE field LIKE "text%" # can use an index

but remember that for index there is a limit of 767 bytes

From Mysql DOC

A B-tree index can be used for column comparisons in expressions that use the =, >, >=, <, <=, or BETWEEN operators. The index also can be used for LIKE comparisons if the argument to LIKE is a constant string that does not start with a wildcard character.
