There are a number of vertical search engines and several specialized tools like Google Scholar that help academics search for scholarly works on the Web. While searching for some documents on an optimization problem, I was curious if there was a good way to search for Mathematical documents on the Web. Most search engines do not have any special means to search for equations or support for special mathematical symbols (like summation or exponent). Many a times one knows the exact term that they are looking for, however sometimes you might be more familiar with an equation or might try to find special terms in a document. I wonder how Mathematicians and Physicists find what they are looking for?

LaTeX is a widely used authoring tool in academia and I believe that support for LaTeX queries would be extremely beneficial for search. At the very least, it would be great if Google Scholar could support this. There are a few prototypes online, but none that I am aware of have the coverage or are free or currently functional.

I see many challenges in parsing and representing mathematical data and it seems like an interesting problem that researchers in information retrieval would have definitely looked into. I would appreciate if anyone familiar with this topic can share some good references.
