[OPEN-ILS-GENERAL] Inconsistent results searching Z39.50

I have been unable to locate a helpdesk ticket. 

I do remember this being reported even though I could not find a ticket for it (which may have meant someone emailed me about it and didn't file a ticket) . However, I think we were unable to replicate it and were never sure whether it was user error or a problem with OCLC at the time since only one library reported it. 

If you want to send the titles you were searching by ISBNs, I can check to see if anything occurs with our interface (although we only search OCLC) for those specific records.

Subject: [OPEN-ILS-GENERAL] Inconsistent results searching Z39.50 

We recently migrated a group of small libraries to Evergreen. All of the libraries are having trouble searching Z39.50. It seems like the search gives up too quickly or just returns without doing the search. 

Here’s an example of the kind of frustration we’re having – we search for the 10-digit ISBN number 1416504973. The Milwaukee Public Library connection should return a record, but the search returns no results about 4 out of 5 times. About 1 out of 5 times the exact same search returns 1 record from Milwaukee. Even with Milwaukee as the only service selected for the search, it returns no results most of the time. It returns within a few seconds whether there are results or not. 

The record I get from Milwaukee from that search also contains a 13-digit ISBN number. If I copy that number and search on it, it fails to return the Milwaukee record (where I got the number) about nine out of ten times. The tenth time it works. 

Does anybody have suggestions for improving the Z39.50 search process? We are still on – will the results be better in version 1.6?
