We present a search engine for mathematical formulae. The
MathWebSearch
system harvests the web for content representations (currently
MathML
and
OpenMath
) of formulae and indexes them with substitution tree indexing, a technique originally developed for accessing intermediate results in automated theorem provers. For querying, we present a generic language extension approach that allows constructing queries by minimally annotating existing representations. First experiments show that this architecture results in a scalable application.
