    I am aware of these examples to filter results by known values
    https://foo/vmrest/globalusers?query=(alias%20is%20MYUSER)
    https://foo/vmrest/globalusers?query=(alias%20is%20MYUSER)
     
    Is there a way to include only those entries where, for example, DtmfAccessId is null or not like XYZ???
