.. note::

There is a important point which you have to care. The ``\`` (backslash)
character is interpreted by command line shell. So if you want to search
``(`` itself for example, you need to escape twice (``\\(``) in command line shell.
The command line shell interprets ``\\(`` as ``\(``, then pass such a literal
to groonga. groonga regards ``\(`` as ``(``, then search ``(``
itself from database. If you can't do intended search by groonga, confirm whether
special character is escaped properly.
