    Description

      http://dev.mysql.com/doc/refman/5.0/en/string-functions.html#function_instr
      http://dev.mysql.com/doc/refman/5.0/en/string-functions.html#function_locate

      These functions can be directly implemented with Text (instead of String). This will make the test of whether one string contains another string much faster.
