Hi Ravi, It seems to me that you are trying to simulate some of highlighting features, but might be wrong. Can you explain your problem not the problem you run into with your solution.
With what you explained, it seems to me that the easiest solution would be to have snippet field that is stored and not indexed and you can use it in your template.
