[Koha-patches] [PATCH 2/2] Bug 12738: C4::Context should set 'keyword' as the default search class

[Tomas Cohen Arazi]

On a Perl 5.18 environment (e.g. Ubuntu 14.04 LTS):

To reproduce:
- Have UseQueryParser == "Don't try"
- Perform a search typing just a word that would have many matches on your Zebra db.
- Take note of the search results count.
- Make sure you have the queryparser.yaml file in your config dir.
- Set UseQueryParser == "Try"
- Perform the same search a couple of times
=> FAIL: Notice that the search results count differs from one run to the other.
- Run the regression tests
  $ prove -v t/db_dependent/QueryParser.t
=> FAIL: tests fail

To test:
- Apply the patch
- Run tests
  $ prove -v t/db_dependent/QueryParser.t
=> SUCCESS: tests pass
- Repeat the steps 'To reproduce'
=> SUCCESS: Search results count is deterministic :-D
- Sign off :-D
