Created attachment 3479 [details] [review] Proposed Patch

Created attachment 3635 [details] [review] Follow-up for exact search, using ext instead of wrdl
setup for testing - authid = 13542 related to biblio 17 - authid = 3542 related to biblio 156 (and 2 others after) after - biblio 17 related to authid 35424 authorities search - finds 3542 (or 13542) and click on 1 biblio -> redirect on this biblio - finds 3542 and click on 3 biblios -> lists 3 biblios in results page I understand what second patch do, it fixes an issue of the first patch but I don't understand and see what the first patch fixes. It works for me.
