How to enable highlighted search functionality? I want to enable search functionality such that: 


I have one word say "school" in my website and if I put "sc" word in search box, then search result should give "school" word with "sc" word highlighted.
I have one word say "school" in my website and if I put "oo" word in search box, then search result should give "school" word with "oo" word highlighted.


How can I solve this problem?
You can use the Highlight module:


  
  Highlight the keywords from referrer search engine
  Highlight the keywords from local search
