Ah, interesting trick! Unfortunately, it doesn't work either (although it
doesn't explode, it just returns zero hits).
I suspect you're right about the server not being configured to support
booleans, which would be a shame.

I can't say anything about the horizon server. But I have a suggestion.
It's possible that server is configured to not support Booleans (either on
that index or at all) and is blowing the trivial error response. If this is
the case, there may be a workaround. Instead of explicitly ORing them
together, maybe you can implicitly OR them together.
The new query would look like this: f @attr 1=7 @attr 4=6 9780413690609
0413690601
What you are telling the server is that you want to search index 7 (use=7)
and the structure of the term is a list of words (structure=6). First you
have to hope this works and second you have to hope that OR is the implicit
operator used in the list. But, it's worth a try. (In SRU we can explicitly
say that this is a list of words to be ORed together.)

Subject: or queries against Horizon Z39.50 servers?
Hi everyone,
I was wondering if anybody knew if there was some secret attribute
combination to successfully do a or-ed ISBN or ISSN query against a
SirsiDynix Z39.50 server. I've tried it against quite a few different
implementations, but they all fail.
From yaz-client, it goes something like this:
Z f @or @attr 1=7 9780413690609 @attr 1=7 0413690601
Sent searchRequest.
Received SearchResponse.
Search was a bloomin' failure.
Number of hits: 0, setno 1
Result Set Status: none
records returned: 1
Diagnostic message(s) from database:
[100] Unspecified error -- v3 addinfo 'Unable to navigate!'
Elapsed: 0.421485
All of the ones I've tried fail with that same error.
If I search on the ISBNs individually, e.g.:
Z f @attr 1=7 9780413690609
Sent searchRequest.
Received SearchResponse.
Search was a success.
Number of hits: 1, setno 2
records returned: 0
Elapsed: 0.606146
it works fine.
If you are able to successfully do or'ed ISBN or ISSN queries can you pass
along all of the use attributes that are being sent?
Thanks,
-Ross.
