When a SuDoc number or keyword search does not return satisfactory results in a Z39.50 client, try replacing all occurrences in your search term of spaces (“ “) with a caret symbol (“^”). For example, to search the SuDoc number “HE 20.7008:H 35”, replace the spaces with carets ( ^) to make it: “HE^20.7008:H^35”.

Here is another option to try:

----------------------------------------------------------------------------------------------
Combine the “use” attribute “u” and the “position” attribute “p” in your
configuration setting table for the CGP. This setting may allow you to search SuDoc
numbers without replacing spaces with carets (^).  Here is a setting example:

find xxx u=50 p=1   --->’xxx’= the code for the 086 SuDoc No. in your ILS.
----------------------------------------------------------------------------------------------

In some Z39.50 free clients, you have to search the SuDoc call number using query language. For example, you can search by ‘RAW (Adv)’ in MarcEdit and
by ‘PQF’ in Mercury: input a search string like this:

-------------------------------------------------------
@attr 1=50 HE^20.7008:H^35
