  80 =head2 extract_biblionumber
  81
  82     my $biblionumber = $searcher->extract_biblionumber( $searchresult );
  83
  84 $searchresult comes from simple_search_compat.
  85
  86 Returns the biblionumber from the search result record.

  94 }
  95
  96 =head2 search_auth_compat
  97
  98 This passes the search query on to C4::AuthoritiesMarc::SearchAuthorities

 112
 113 =head2 max_result_window
 114
 115 Returns the maximum number of results that can be fetched
 116
 117 Zebra does not have such a limit, so it always returns undef
