Neat! There's also Lightgrep. https://github.com/LightboxTech/liblightgrep https://github.com/LightboxTech/liblightgrep Lightgrep also supports a subset of PCRE and scales pretty well with the number of patterns (has done millions of fixed strings). Lightgrep is designed for digital forensics, so it searches data as a binary stream. Lightgrep also supports searching for patterns in multiple encodings, with no requirements on the underlying data. Lightgrep is GPL. (I'm one of the authors of Lightgrep.)
