SharePoint 2010 search webservices compatibility with SharePoint 2013

Question

Please let us know whether the SharePoint 2010 search webservice is compatible with SharePoint 2013.
When we try to hit the SharePoint 2013 search service with the query developed in the Sharepoint 2010 , we are getting "System.Not supported" exception as response from server.
Below is the search query we are using:
"<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">"
            + "<soap:Body>"
            + "<Query xmlns=\"urn:Microsoft.Search\">"
            + "<queryXml>"
            + "&lt;QueryPacket xmlns=\"urn:Microsoft.Search.Query\"&gt;"
            + "&lt;Query&gt;"
            + "&lt;Range&gt;&lt;StartAt&gt;1&lt;/StartAt&gt;&lt;Count&gt;50&lt;/Count&gt;&lt;/Range&gt;"
            + "&lt;SupportedFormats&gt;"
            + "&lt;Format&gt;urn:Microsoft.Search.Response.Document:Document&lt;/Format&gt;"
            + "&lt;/SupportedFormats&gt;"
            + "&lt;Context&gt;"
            + "&lt;QueryText type=\"MSSQLFT\"&gt; SELECT fileName,Title,Path,Write,SiteName,URL,FileExtension,isDocument,contentClass FROM scope() WHERE CONTAINS(Path, SITE_PORT)
and (contentClass = 'STS_Web' OR contentClass = 'STS_ListItem_DocumentLibrary' OR contentClass = 'STS_List_DocumentLibrary') ORDER BY lastModifiedTime DESC &lt;/QueryText&gt;"
            + "&lt;/Context&gt;"
            + "&lt;/Query&gt;"
            + "&lt;/QueryPacket&gt;"
            + "</queryXml>"
            + "</Query>"
            + "</soap:Body>"
            + "</soap:Envelope>";
Please  help

Hi Raghuramk,
is the web service is a search query web service? if yes, i suppose sharepoint 2013 already deprecated,
Search Query web service
Description: The Search Query web service is deprecated in SharePoint 2013.
In SharePoint Server 2010, the Search Query web service exposes the SharePoint Enterprise Search capabilities to client applications. This enables you to access search results from client and web applications outside the context of a SharePoint site.
Reason for change: The Search Query web service is deprecated because the client object model (CSOM) and a new REST-based web service are available for developing Office-wide extensibility scenarios. The CSOM exposes the same functionality
as the Search Query web service, and a larger set of functionality for stand-alone client applications.
