I have done search using FTSearch and after searching list of document appears then I open the particular document which contains javascript in a particular field with the url

http://servername/databasename/0/uniqueID?opendocument&Highlight=Javascript

But it is not highlighting the javascript word in the field. What is the way to highlighting word in the field.
