With col_name (n) syntax in an index specification for a string column, you can create an index that uses only the first n characters of the column. The best way to improve the performance of select operations is to create indexes on one or more of the columns that are. My main point is that indexing a single boolean field is almost never useful.

However, if you have multiple boolean fields, and your search will. This is particularly true for boolean fields, which have only two possible values (true or false).
