Bug 13278: t/Search.t shouldn't depend on the DB

Bug 13278: t/Search.t shouldn't depend on the DB

To reproduce:
- Stop your MySQL server:
  $ sudo service mysql stop
- Run
  $ prove t/Search.t
=> FAIL: some tests fail because of mysql stopped

To test (MySQL still stopped)
- Apply the patch
- Run
  $ prove t/Search.t
=> SUCCESS: tests pass because the ycan be loaded regardless of
            the absence of the DB server
- Sign off :-D

Turned off MySQL and ran the tests before and after the patch.
Works as advertised.
