I’ve made a lot of internal changes and improvements to the C++ part of pytst in order to implement an incremental full text index with both Python and COM bindings.

The only visible change of the pytst 1.0.6 distribution is a more compact serialisation format. It’s not top notch compression, but it saves about 25% of disk space.

For top notch compression, I’m currently reading Managing Gigabytes, an excellent book about compression and documents (text and images) indexation. It’s very interesting and pretty inspirative. It’s rather old, though, for example the index mentions Excite and Altavista but not the small but promising Google search engine. But it’s a theory book and most of the theory hasn’t changed in 10 years, of course.
