This happens a lot: I am reading a paper, as usual going directly to the results and skipping the introduction, related literature, discussion, preliminaries, formal model etc. And then there is some which I have no idea what it stands for. I would like to search for `\alpha’ in the pdf document, but if there is a way to do it then I have never heard about it.
So, imagine my delight when I heard of Springer’s LaTeX Search tool, which does something that I never even dared to wish — search in their database for an equation that contains a given latex code. Pretty awesome, isn’t it ?
I tried some arbitrary code
i\hbar\frac{\partial}{\partial t}\Psi=\hat H\Psi
(which translates to )
but apparently nobody has used this equation before.
So I tried something else: E=mc^2. Again no exact matches but this time there are a couple of similar results
Well, as Jeffrey Shallit said, it is, at least, a start.

I’ve created a similar site recently – http://uniquation.com In some cases it works better than http://latexsearch.com
It indexes popular Q&A sites (http://math.stackexchange.com and http://mathoverflow.net) and wikipedia. It supports basic arithmetic expressions, integrals, common operators like (\sin, \cos …), function calls and low indexes (like f(x)=… or x_n), differential equations, sums and limits.
So, the current version can be useful for differential equations, Diophantine equations, number theory and math analysis related searches.
