Acora is 'fgrep' for Python, a fast multi-keyword text search engine.
Based on a set of keywords and the Aho-Corasick algorithm, it generates a
search automaton and runs it over string input, either unicode or bytes.
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).
