www.formulasearchengine.com deals about making math searchable.
In mathematics, physics and engineering text search is helpful but not sufficient, since some knowledge is convoyed in mathematical formulae only. As a consequence one needs to perform search queries that involve formula and text.
Today there are attempts to perform formula search (see current formula search engines) but none of them has evolved to the standard formula search tool in science. One reason could be that the user interfaces are not very well designed. Furthermore the lack of understanding the context in which the formula appears is an open problem.
Therefore the aim of www.fomulasearchengine.com is to build a context aware text and formula search engine.
The current prototype of the search engine can be found online.
