You can query with a regular expression   db users find   name    m       If the string is coming from the user  maybe you want to escape the string before using it  This will prevent literal chars from the user to be interpreted as regex tokens   For example  searching the string  A   will also match  AB  if not escaped  You can use a simple replace to escape your string before using it  I made it a function for reusing   function textLike str      var escaped   str replace    -                                g       amp       return new RegExp escaped   i        So now  the string becomes a case-insensitive pattern matching also the literal dot  Example    gt   textLike  A      lt    A   i   Now we are ready to generate the regular expression on the go   db users find    name   textLike  m
