Hi,I was able to define the operator with following XML
<options xmlns="http://marklogic.com/appservices/search";>       <operator 
name="sort">          <state name="postedon">                 <sort-order 
type="xs:date" direction="ascending">                               
<json-property>postedon</json-property>                 </sort-order>           
</state>        </operator></options>
I can confirm this when I check in http://localhost:8040/v1/config/query
But now I am not able to use it in my Search API, I am using the following url 
to verify the sort orderhttp://localhost:8040/v1/search?q=2015%20sort:postedon
I am not getting any results with the sort:postedon. I have create Element 
Range index & Field Range index on postedon of type date.
Do I need any other index to influence the sort order of my results? is the 
definition of the operator right?Any tips on debugging it further would be 
helpful.
regards,Puneet

Subject: [MarkLogic Dev General] Search API : defining a new operator




Hi,I am trying to define an operator sort:postedon to sort the search results 
in descending order of the date (json-property is postedon). I am using ML8 and 
my data is JSON files only. Following is my xml file
<options xmlns="http://marklogic.com/appservices/search";> <search:operator 
name="sort">     <search:state name="postedon">        <search:sort-order 
direction="descending" type="xs:date">           <search:element ns="" 
json-property="postedon"/>        </search:sort-order>        
<search:sort-order>           <search:score/>        </search:sort-order>     
</search:state> </search:operator></options>
And I am applying this search option using following command
curl -v -X PUT  --digest --user admin:admin  -H "Content-type: application/xml" 
-d @./SortOrder.xml 'http://localhost:8040/v1/config/query/sortorder'
On running the command I am getting the following error








{"errorResponse":{"statusCode":500, "status":"Internal Server Error", 
"messageCode":"INTERNAL ERROR", "message":"XDMP-DOCNONSBIND: 
xdmp:get-request-body(\"xml\") -- No namespace binding for prefix search at  
line 1 . See the MarkLogic server error log for further detail."}}
Following is the entry in the server log
2015-05-09 21:05:49.176 Notice: carsearch: XDMP-DOCNONSBIND:

following the examples in manuals 
athttps://docs.marklogic.com/guide/search-dev/query-options#id_30002
is the namespace "http://marklogic.com/appservices/search"; right?
Any tips to resolving it would be useful.regards,Puneet
