Searching for equations

Thanks everyone for the replies. I like Google because it searches ps 
and pdf files (and I've found a number of useful papers that way), but 
there isn't an escape character (that I know of, anyway) which will 
treat symbols such as + and - as literal characters. Do any of the other 
search engines do this? One route is searching Math ML marked text. The 
other would be doing literal searches for ASCII-formatted equations. I 
think between those two methods I can get relatively decent results.
