[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?
