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

I searched the Milwaukee catalog directly and did not return any item with the ISBN1416504973. Nor did I find it on WorldCat or Amazon. Is it the correct ISBN ? 

For the 13 digit ISBN you copied, make sure you haven't copied any extraneous characters. At least searching OCLC via Z39.50, sometimes an unnoticed space at the end or beginning of a number search can cause problems. 

That being said, we had a library report the same problems searching OCLC via the interface. I will see if I can find the helpdesk ticket to see how it was resolved.

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?
