I'm searching a way to find text spanning multiple nodes in similar way Firefox does it, eg.

With given HTML:

```
<p>Lorem ipsum <b>dolor</b> sit amet.</p>

```

When I search for text "ipsum dolor" by ctrl+f Firefox will selects that text, ie. will create Range object(s).

I know I can easily search for text within text nodes (vide [Find text string using jQuery?](https://stackoverflow.com/questions/926580/find-text-string-using-jquery)) but this doesn't work in above example.
