This patch adds a few basic search and indexing tests for UNIMARC,
using sample data provied by Frédéric Demians. The new tests
by no means completely cover the possibilities, but should be
considered a starting point for future tests.
To test:
[1] Verify that prove -v t/db_dependent/Search.t passes.
