Math-aware search engines are required to effectively retrieve mathematical documents including various equations. In this paper, we propose a mathematical document retrieval system by which users can retrieve documents using any combination of keywords and equations. The proposed system indexes equations and their surrounding keywords from mathematical documents. Then, it searches and ranks mathematical documents using a language model modified for the heterogeneous indexing units (i.e., mixtures of equations and keywords). In the experiments, the proposed system performed well, especially for high ranks.
