How to implement highlighting in the browser?

I have to say: I am far from the front end and brought it to me randomly at work in him. The bottom line is this: our application has a browser engine to chromium(it is very limited in functionality), through which we display the content of the email. Example - . We need to implement the highlighting of some words, if any in the document. Tried mark.js he copes, but if in chrome using ctrl+f to enter the letter "1 invitation", it is highlighted. If using mark.js no. Is there some other alternative?
