The core engine is a high level interface to PyLucene, which is a Python extension for accessing the popular Java Lucene search engine.
Lucene has a reputation for being a relatively low-level toolkit, and the goal of PyLucene is to wrap it through automatic code generation.
So although PyLucene transforms Java idioms to Python idioms where possible, the resulting interface is far from Pythonic.
It also provides a RESTful JSON search server, based on the renowned CherryPy.
Many Python applications which require better search capabilities are migrating from using conventional client-server databases, whereas Lucene is an embedded search library.
Solr is a popular option for remote searching and other advanced features, but then any customization or embedded use is coupled to Java and XML.
Using a python web framework instead can provide the best of both worlds, e.g., batch indexing offline and remote searching live.
A simple client to make interacting with the server as convenient as an RPC interface.
It handles all of the HTTP interactions, with support for compression, json, and connection reuse.
