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 the latest version of Java Lucene, version 2.9.0 as of October 13th, 2009.

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.

Zoie is a real-time search and indexing system built on Apache Lucene. In a real-time search/indexing system, a document is made available as soon as it is added to the index. This functionality is especially important to time-sensitive information such as news, job openings, tweets etc.

Slitscan imaging techniques are used to create static images of time-based phenomena. In traditional film photography, slit scan images are created by exposing film as it slides past a slit-shaped aperture. In the digital realm, thin slices are extracted from a sequence of video frames, and concatenated into a new image.

Comparing Python and Java

A programmer can be significantly more productive in Python than in Java.

How much more productive? The most widely accepted estimate is 5-10 times. On the basis of my own personal experience with the two languages, I agree with this estimate.
