Pyndex

Pyndex is a simple and fast full-text indexer implemented in Python. Pyndex also includes an easy to use Bayesian classifier. It uses Metakit as its storage back-end. It works well for quickly adding a search feature to an application, and is also well suited to in-memory indexing and searching. It can handle phrase queries. It performs best in applications involving a few thousand documents, but its scaling is mostly limited by available memory.
