Hello, I've been making use of the wiki documentation at 

https://wiki.evergreen-ils.org/doku.php?id=evergreen-admin:sru_and_z39.50

when I need to setup and test the Z39.50 server.

There is a section for testing the Z39.50 server using the yaz-client.  But it always confuses me because the example shows example searches that don't work.  And there wasn't an example that shows how to search using Z39.50 bib attributes. (I added one).

I would like to remove the examples of non working searches, unless it is just something that I'm doing wrong.

It seems to me that CQL search syntax doesn't work for Z39.50, that only works for SRU.  RPL is the only search syntax that works.

So the example of

Z> find "dc.title=zone and dc.author=king"

is in CQL but gets sent as a server choice search for the keywords "dc.title=zone and dc.author=king" and doesn't return anything.

The next example of 

Z> find "dead zone"  returns results because it gets sent as a serverchoice query which is keyword by default.

Is my understanding correct?  Does it make sense to remove that CQL example?
