Amazing response, thanks. I'll give this a try.

I'll be darned, it worked. High five.

Andrew,

One thing I have just noticed with this is i have on my project made the searching wildcard search which all works however the highlight stops working. Very strange as I have used wildcard search and syntax highlight in the past although it was with older version of lucene.  Going to dig around and little and see if i can get to the bottom of it.

Regards

Ismail

Andrew,

Quick update if you are doing wild card searches then the code needs to change slightly,

 protected const string GeneratedQuery = "+bodyText:{0}*";

and

        private static Query GetLuceneQueryObject(string q,string field)
        {

            var qt = new QueryParser(field, new StandardAnalyzer((Lucene.Net.Util.Version.LUCENE_29)));
            qt.SetMultiTermRewriteMethod(MultiTermQuery.SCORING_BOOLEAN_QUERY_REWRITE);
            return qt.Parse(q);

        }

the main change is the setmultitermrewritemethod if you dont have this then for wildcard queries it wont highlight.

Hey.. I tryed to use the example, but I can't get the repeater to call the GetSearchResultHighlight method? Any suggestions to what I'm doing wrong? The only thing I have changed in the example is the LUCENEINDEX.

Henrik,

I take it you are getting some search results? Also what happens when you step through after adding break point on the method does it get called?

Ismail

Thanks for your time. I got it to work now, made a stupid mistake :(

@ Ismail, 

I have  search results with examineUmbraco pdf, but the razor script does not render the link to the files. 

can you help? 

here is my razor: 

Thanks.

@using Examine
@using Examine.SearchCriteria
@using UmbracoExamine
@using UmbracoExamine.PDF
@using umbraco.MacroEngines
@using System.Xml.Linq
@using umbraco.presentation.nodeFactory
@using umbraco.cms
@using umbraco.cms.businesslogic.media;
@inherits umbraco.MacroEngines.DynamicNodeContext

@{
      var searchString = Request["searchstring"];
      if (!String.IsNullOrEmpty(searchString))
  {          
    var searchResults = ExamineManager.Instance.SearchProviderCollection["PDFSearcher"].Search(searchString, true);
    foreach (var c in searchResults)
    {    
    <div>
        
<p><a href="http://localhost:22841/Media/@c.Fields[@"__NodeId"]">@c.Fields[@"__NodeId"]</a></p>
         
        
    

        
        @if(c.Fields.Keys.Contains("FileTextContent"))
        {
          var bodyText = c.Fields["FileTextContent"];
          <p>@Html.Raw(bodyText.Substring(0,100))</p>
        }
      </div>
          
    }
   
  }

}

The node id is not the media folder id so it wont work.  You need to get the media item using node id then get url I have an extension method for it

        /// <summary>
        /// returns result url depending on type
        /// </summary>
        /// <param name="s">object searchresult</param>
        /// <returns>full url of object</returns>
        public static string FullUrl(this SearchResult s)
        {
            string url = umbraco.library.NiceUrl(s.Id);
            if(url==string.Empty)
            {
                var m=new Media(s.Id);
                url = m.getProperty("umbracoFile").Value.ToString();
            }

            return url;

        }

Regards

Ismail

@ Ismail

Thanks for this. 

I have not used extension methods in umbraco before. Do I need to place this code in App_Code and call the method in razor script? 

Could you offer a bit of guidance on extension methods in Umbraco? 

I am using umbraco 4.11 and the examples on extension methods that I have  found out are not working for my umbraco version. 

Thanks 

D

take a look at http://msdn.microsoft.com/en-gb/library/vstudio/bb383977.aspx

you can put in app_code or your own dll

What text needs to be passed for the parameter LuceneIndex? Is it the IndexSet name that I have in my ExamineIndex.Config?

ExtensionMethods.GetHighlight(sr.Fields["bodyText"],LuceneIndex,
                                                               string.Format(GeneratedQuery,
                                                                             Request.QueryString["search"]),"bodyText");

Dear Ismail, Thank you so much for the great article.

I am a newbee to Examine. I have implemented the search and got the highlighted text by using your code. But how can I find inside words? Like if I search for "is", my search should also return all the words which contain "is" at any position.

Any help would be appreciated.

Umair,

I am assuming you are referring to the post above by Pradeep? If so then LuceneIndex parameter is the index you are looking at.  To get the generated query you do criteria.ToString() see http://thecogworks.co.uk/blog/posts/2012/november/examiness-hints-and-tips-from-the-trenches-part-1/

Dear Ismail, I got it working. Thanks. I have updated my question. Please help me in that too.
