Bug 10766: unbreak reservoir search when UseQueryParser is OFF

To test:

[1] Turn UseQueryParser off.
[2] Ensure that your database has records in the reservoir.  Performing
    a Z39.50 search will do this.
[3] Perform a broad cataloging (i.e., cataloguing/addbooks.pl search).
    Note that results are returned from the main catalog but that no
    reservoir results are returned.
[4] Apply the patch.
[5] Perform the search again.  This time, there should be both catalog
    and reservoir results.
[7] Enable QueryParser.  Perform the search again, and verify that the
    catalog and reservoir results are the same.

Patch works nicely, passes all tests, and the QA script.
