Welcome to PyLucene
What is PyLucene ?
PyLucene is a Python extension for accessing Java Lucene™. Its goal is to allow you to use Lucene's text indexing and searching capabilities from Python. It is API compatible with Java Lucene version 9.7.0 as of July 12th, 2023.
PyLucene is not a Lucene port but a Python wrapper around Java Lucene. PyLucene embeds a Java VM with Lucene into a Python process. The PyLucene Python extension, a Python module called lucene is machine-generated by JCC.
PyLucene is built with JCC, a C++ code generator that makes it possible to call into Java classes from Python via Java's Native Invocation Interface (JNI). Sources for JCC are included with the PyLucene sources.
See here for more information and documentation about PyLucene.
Requirements
PyLucene is supported on macOS, Linux, Solaris and Windows.
PyLucene requires Python 3.x (x >= 3), and Java x (x >= 8 for PyLucene 8 and earlier, x >= 11 for PyLucene 9). Python 2 support is untested since PyLucene 9.4.1 / JCC 3.13. Building PyLucene requires GNU Make and a C++ compiler. Use of setuptools is recommended.
See the JCC installation instructions for more information about building JCC from sources.
