DASL Search Not giving Result

[aslam bari]

Hello all,
  I have used LuceneContentIndexer for content indexing and 
LucenePropertiesIndexer for Property indexing. store/index_metadat is 
successfully getting created with many index files. But /index_conent has only 
segment file. Any way i use the following search but it does not giving me any 
result. 
  "<?xml version=\"1.0\" encoding=\"utf-8\" ?>\n" +
  "<D:searchrequest xmlns:D =\"DAV:\">" +
  "<D:basicsearch>" +
  "<D:select>" +
  "<D:prop>" +
  "<D:getcontentlength/>" +
  "<D:displayname/>" +
  "</D:prop>" +
  "</D:select>" +
  "<D:from>" +
  "<D:scope>" +
  "<D:href></D:href>"+
  "<D:depth>infinity</D:depth>" +
  "</D:scope>" +
  "</D:from>" +
  "<D:where>" +
  
"<D:like><D:prop><D:displayname/></D:prop><D:literal>Open%</D:literal></D:like>"
 +
  "</D:where>" + 
  "</D:basicsearch>" +
  "</D:searchrequest>";
   
   
  If i am missing something?
