If your query is always a simple, logical OR of a series of words, then the fastest way to gather the information you mention would be to run individual term queries for each search word. This way your code will know which documents contain each term and your code can then assemble the combined result list with this information.

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); //Field ff = objDocument.GetField(SearchFor); //Extract the data string strPath = objDocument.Get("path"); string strFileName = objDocument.Get( "filename"); string strcontents = objDocument.Get( "contents"); string preview = GeneratePreviewText(obj, strcontents); strcontents = preview; 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>" + strcontents + "</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; } public string GeneratePreviewText(Query q, string text) { QueryScorer scorer = new QueryScorer(q); Lucene.Net.Highlight.Formatter formatter = new Lucene.Net.Highlight.SimpleHTMLFormatter("<span style='background:red;'>", "</span>"); Highlighter highlighter = new Highlighter(formatter, scorer); highlighter.SetTextFragmenter(new SimpleFragmenter(250)); TokenStream stream = new StandardAnalyzer().TokenStream( "contents", new StringReader(text)); return highlighter.GetBestFragments(stream, text, 4, "<br/>"); } 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. In the GeneratePreviewText i am able to highlight the keywords in the content but how do i tag it as separate Record and tag to each file as below No FileName KeyWord(s)Found 1 Test.Doc karthik 2 Test2.Doc steven i hope u guys understood the question, Thanks and Regards Karthik Davanam Rolls-Royce, Tata Consultancy Services Pioneer Building, International Tech Park, Padandhur Agrahara, Whitefield Road, Bangalore - 560066,Karnataka India Cell:- +919731600998 Mailto: karthik.dava...@tcs.com Website: http://www.tcs.com ____________________________________________ Experience certainty.
