Defined indexes in pqf.properties must refer to a valid index in biblios/etc/bib1.att. Out of the box: * index.dc.branch is mapped to 1=1033 in pqf.properties * att 1033 is mapped to 'Host-item' in bib1.att * index.dc.branch should be mapped to 'homebranch' * att 8011 is mapped as 'homebranch' in bib1.att Given the above, pqf.properties should be updated to map index.dc.branch to 1=8011.
