Okapi BM25. In information retrieval, Okapi BM25 ( BM is an abbreviation of best matching) is a ranking function used by search engines to estimate the relevance of documents to a given search query. It is based on the probabilistic retrieval framework developed in the 1970s and 1980s by Stephen E. Robertson, Karen Spärck Jones, and others.
OpenGrok. OpenGrok is a source code cross-reference and search engine. It helps programmers search, cross-reference, and navigate source code trees to aid program comprehension . It can read program file formats and version control histories such as Monotone, Subversion, Mercurial, Git, ClearCase, Perforce, AccuRev, Razor, and Bazaar. [2]
Sphinx is configured to examine a data set via its Indexer. The Indexer process creates a full-text index (a special data structure that enables quick keyword searches) from the given data/text. Full-text fields are the resulting content that is indexed by Sphinx; they can be (quickly) searched for keywords. Fields are named, and you can limit ...

Unless semantics of Python are changed, but in many cases speedup is possible with few or no changes in the Python code. The faster Julia source code can then be used from Python, or compiled to machine code, and based that way. Nuitka compiles Python into C. Numba uses LLVM to compile a subset of Python to machine code. Pythran compiles a ...
