lucene-c-boost | Implements common Lucene queries in C via JNI

lucene-c-boost is a C++ library. lucene-c-boost has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Optimized implementations of certain [Apache Lucene] queries in C++ (via JNI) for anywhere from 0 to 7.8X speedup:. The gains come from 1) code specialization (creating dedicated code to execute exactly one kind of query, with nearly all abstractions removed), and 2) using C++ instead of Java. It's not yet clear how much of the gains are due to each. The code is fully decoupled from Lucene: it uses Java's reflection APIs to grab the necessary bits for each query. This is NOT a port of Apache Lucene to C++! Rather, it implements hardcoded C++ code to optimize certain queries. The optimizations are very narrow: they only apply for specific queries. This is a spinoff from LUCENE-5049. This project is very new and exploratory at this point. Use at your own risk! (But please provide feedback if you do).
