Rest driver publisher Query not working as per document

We integrated Rest Driver and enable publisher APIs. 

As per the configuration based on document, ADD (Post method), Modify (PUT Method) is working. 

User creation and modification is working as expected. 

But in the case of Query (GET method) generating and 200 response is coming, but not returning any search result.

GET Request :  

ipaddress:port/User name eq
‘test*user’ and cn eq ‘test*’&read-attr=title

But response is not coming. 

Please suggest me the reason for this.
