whatever source script will do. As long as it can detect my website content for visitor convenience..that's enough, the search engine doesn't need to relate with any other websites's content.

Just like if my company is selling various type of accessories. Then visitor able to search any type of accessories that they wan..like if he wants to buy car accessories. Then he search for car's sterring. Then the indexing will display which page of my website are showing car's sterring..
