Thank you Galen, I appreciate you taking the time to look into this. I'll update the wiki page and add a new example showing how to setup CQL searching. Josh On Fri, Jun 13, 2025 at 4:50 PM Galen Charlton <gmc@equinoxoli.org> wrote:

Is my understanding correct? Does it make sense to remove that CQL example?
It probably does, since most Z39.50 clients will just send RPN queries anyway, but you could make the example work by doing the following:
[1] Create a CQL mapping file something like this
set.cql = http://www.loc.gov/zing/cql/context-sets/cql/v1.1/ set.dc = http://www.loc.gov/zing/cql/dc-indexes/v1.0/ index.cql.serverChoice = 1=1016 index.dc.title = 1=4 index.dc.author = 1=1003 index.dc.subject = 1=21 relation.< = 2=1 relation.eq = 2=3 relation.scr = 2=3 position.any = 3=3 6=1 structure.* = 4=1
(This was adapted from example 7.10 of https://software.indexdata.com/yaz/doc/yaz.pdf)
[2] Run yaz-cilent like this:
yaz-client localhost:9999/CONS -q cql_mapping_file Z> querytype cql2rpn Z> find dc.title="throne of the crescent moon" and dc.author="ahmed" Sent searchRequest. Received SearchResponse. Search was a success. Number of hits: 1, setno 1 records returned: 0 Elapsed: 0.084814
