searching file content lucene.net

Lucene.NET

I am currently using lucene.net to search the content of files for keyword search. I am able to get the results correctly but I have a scenario where I need to display the keywords found in a particular file.
There are two different files containing "karthik" and "steven", and if I search for "karthik and steven" I am able to get both the files displayed. If I search only for "karthik" and "steven" separately, only the respective files are getting displayed.
When I search for "karthik and steven" simultaneously I get both the files in the result as I am displaying the filename alone, and now I need to display the particular keyword found in that particular file as a record in the listview.
enter code here

==Code====
Public bool StartSearch()
{
bool bResult = false;
Searcher objSearcher = new IndexSearcher(mstrIndexLocation);
Analyzer objAnalyzer = new StandardAnalyzer();
try
{
//Perform Search
DateTime dteStart = DateTime.Now;
Query objQuery = QueryParser.Parse(mstrSearchFor, "contents", objAnalyzer);
Hits objHits = objSearcher.Search(objQuery, objFilter);
DateTime dteEnd = DateTime.Now;
mlngTotalTime = (Date.GetTime(dteEnd) - Date.GetTime(dteStart));
mlngNumHitsFound = objHits.Length();
//GeneratePreviewText(objQuery, mstrSearchFor,objHits);
//Generate results - convert to XML
mstrResultsXML = "";
if (mlngNumHitsFound > 0)
{
mstrResultsXML = "<?xml version=\"1.0\" encoding=\"UTF-8\" ?><Results>";
//Loop through results
for (int i = 0; i < objHits.Length(); i++)
{
try
{
//Get the next result
Document objDocument = objHits.Doc(i);
//Extract the data
string strPath = objDocument.Get("path");
string strFileName = objDocument.Get("name");
if (strPath == null) { strPath = ""; }
string strLastWrite = objDocument.Get("last_write_time");
if (strLastWrite == null)
strLastWrite = "unavailable";
else
{
strLastWrite = DateField.StringToDate(strLastWrite).ToShortDateString(); }
double dblScore = objHits.Score(i) * 100;
string strScore = String.Format("{0:00.00}", dblScore);
//Add results as an XML row
mstrResultsXML += "<Row>";
//mstrResultsXML += "<Sequence>" + (i + 1).ToString() + "</Sequence>";
mstrResultsXML += "<Path>" + strPath + "</Path>";
mstrResultsXML += "<FileName>" + strFileName + "</FileName>";
//mstrResultsXML += "<Score>" + strScore + "%" + "</Score>";
mstrResultsXML += "</Row>"; } catch { break;

}

} //Finish off XML
mstrResultsXML += "</Results>";
//Build Dataview (to bind to datagrid

DataSet objDS = new DataSet();

StringReader objSR = new StringReader(mstrResultsXML);
objDS.ReadXml(objSR);
objSR = null;
mobjResultsDataView = new DataView();
mobjResultsDataView = objDS.Tables[0].DefaultView;
}
//Finish up
objSearcher.Close();
bResult = true;
}
catch (Exception e)
{
mstrError = "Exception: " + e.Message;
}
finally
{
objSearcher = null;
objAnalyzer = null;
}
return bResult;
}


Above is the code i am using for search and the xml i am binding to the listview, now i need to tag the particular keywords found in the respective document and display it in the listview as recordsss,simlar to the below listview
