Fast multi-keyword search engine for text strings

Acora is 'fgrep' for Python, a fast multi-keyword text search engine. Based on a set of keywords, it generates a search automaton (DFA) and runs it over string input, either unicode or bytes. It is based on the Aho-Corasick algorithm and an NFA-to-DFA powerset construction. Acora comes with both a pure Python implementation and a fast binary module written in Cython. However, note that the current construction algorithm is not suitable for really large sets of keywords (i.e. more than a couple of thousand).
