At present, the QueryParser search mode expects that search field names
and aliases are case-sensitive. This may change (see bug 11353), but
for now, this patch ensures that the local-number searches used by
the KohaBiblio rule will work regardless of the value of the
UseQueryParser system preference.
To test:
[1] Use the KohaBiblio 999$c matching rule with UseQueryParser both
on and off. Verify that matching by biblionumber works correctly.
