    I checked the IIndexerInfo and it only defines the following:



    Culture { get; }



    Encoding Encoding { get; }



    Guid ItemID { get; }



    string MimeType { get; }



    string Path { get; }



    byte[] GetData();

    My question is, if this is the only implemented by the IIndexerInfo how will I be able to add another property like for example I want to add "string Title {get;}" in order to be used by my CustomSearchIndex and be added to its return result?

    Hello Roland,

    Generally the Interface public properties cannot be changes and you cannot add new one. I am not sure for which item type you want to get the title, but I will give you some samples that covers most of the cases.

    If you want to make the title searchable ( let's say for a icontent item) you can edit
    ~/App_Data/Search/YOUR_INDEX_NAME/fieldsInfoProvider.xml and add the field there

    <?xml version="1.0" encoding="utf-8"?> 
      <field name="title" weight="1" indexAttribute="" filterTag="title" filterAttributes="" /> 

    The fields you are adding should be registered as metafields and set as searchable in the web.config.

    Another way is implementing the following logic in your custom provider

        public MyIndexer() 
        public string MimeType 
                // specify the mime type which will be searched 
                return "text/html"
        public byte[] GetData() 
            string text = "my content"
            // here we are searching between title tags of the html 
            text = text + "<title>" + "your title" + "</title>"
            // encode to text 
            return this.Encoding.GetBytes(text); 

    If your requirement is different, let us know.
