Searching in files containing "/" character

How would an user escape the "/" in an inside file search? For example searching for "example/reviews.html"?

Search for example//reviews.html -- i.e. double the /

If it's possible that "example/reviews.html" may be the entire contents of the file, also turn on wildcards to work around a problem we just found. (If the file is shorter than the string it won't be searched.)

FWIW, we are considering removing the / stuff as it seems more confusing than useful, so in future a simple search on example/reviews.html should work.

Thanks Leo, i will forward those infos.
