This article describes how mathematical content items and formulae are processed, retrieved, and accessed in ActiveMath. Central to the retrieval and access is a search tool which allows for searching text, attributes, relations and formulæ, and presenting items. The search tool has been evaluated according to the standard measures of precision and recall as well as for usability. We report results of these evaluations.
