Is there a pure Python Lucene?

The ruby folks have Ferret. Someone know of any similar initiative for Python? We're using PyLucene at current, but I'd like to investigate moving to pure Python searching.

Whoosh is a new project which is similar to lucene, but is pure python.

The only one pure-python (not involving even C extension) search solution I know of is Nucular. It's slow (much slower than PyLucene) and unstable yet.

We moved from PyLucene-based home baked search and indexing to Solr but YMMV.

I recently found pyndexter. It provides abstract interface to various different backend full-text search engines/indexers. And it ships with a default pure-python implementation.

These things can be disastrously slow though in Python.

For some applications pure Python is overrated. Take a look at Xapian.

lupy was a lucene port to pure python.The lupy people suggest that you use PyLucene. Sorry. Maybe you can use the Java sources in combination with Jython.
