 Find some text in the DOM. The difference between this and [other](http://www.gotoquiz.com/web-coding/programming/javascript/highlight-words-in-text-with-jquery/) [Plugins](http://johannburkard.de/blog/programming/javascript/highlight-javascript-text-higlighting-jquery-plugin.html) is that it looks for text in multiple nodes. It uses [DOMRanges](http://www.w3.org/TR/DOM-Level-2-Traversal-Range/ranges.html) and therefor it doesn't works in IE < 10.
 
+Add [jquery.ba-each2.js](http://benalman.com/projects/jquery-misc-plugins/#each2) to improve the speed.

 ## Usage ##
 
 You can find some examples [here](http://fweinb.github.com/jqueryhighlight/).
