How to search a pdf after opening it from a new intent?

I've used the code from the PDF rendering question

How to render PDF in Android

And it works! Props to the answerer, but my question is about doing that same thing but also sending a keyword to search 开发者_StackOverflow社区in the pdf. I have no idea how to do this, should I set a flag? Any help would be greatly appreciated.
