I tried to create a custom search using this URL : catalogue.bibliothequesdequebec.qc.ca/uhtbin/cgisirsi.exe/x/0/0/57/5?searchdata1={query}&srchfield1=GENERAL^SUBJECT^GENERAL^^Mots/expression&searchoper1=&thesaurus1=GENERAL&search_entries1=GENERAL&search_type1=SUBJECT&special_proc1=Mots/expression&library=ALL&match_on=KEYWORD&user_id=WEBSERVER but when i try to use it, it does nothing. When I use this address replacing the {query} in my browser, it works. Is there something not correct in this URL? Thank you for your help.
