I am pleased to announce the first release candidate of TextIndexNG V 1.0.
TextIndexNG is a pluggable index for the ZCatalog that
enhances the full text indexing capabilities of Zope by
providing the following features:
* support for document converters (HTML, PDF, WinWord, PowerPoint,
Postscript). Custom converters can be easily added
* stemmer support for 12 languages
* support for right truncation
* similarity search (soundex, metaphone support) (for english)
* NEAR search
* phrase search
* pluggable query parsers (two parsers included)
* stop words support
* new test tab for interactive testing
* 2-3 times faster than Zopes TextIndex (more to come ;-) )
* compatible with ASCII, ISO-8859-1
Requirements:
* Zope 2.5 or Zope CVS trunk checkout
Documentation:
* http://www.zope.org/Members/ajung/TextIndexNG/wiki/
Download:

Installation:
* The installation is described in the Wiki (see above)
Changes since alpha 2:
* added new PyQueryParser (implements the same query syntax
as QueryParser but it is a native Python implementation that will
run on all platforms and does no longer require flex/bison). The
benefits are locale support and unicode support on the parser level.
* deprecated and removed QueryParser module
* fixed memory leak in C extension for lexicons
* added support for right trunctation to CLLexicon
* right truncation is now always enabled (Lexicons are now using BTrees
only instead of optimal dictionaries for better performance)
