I am pleased to announce the release of TextIndexNG V 3.0.2.

TextIndexNG V 3 is a complete new implementation based on Zope 3 
technologies and can be used both in Zope 2.8 or 2.7 (with Five) or in
Zope 3.

What's new?

 - multi-field indexing and query support

 - multi-lingual support

 - configurable converters (through ZCML)

 - new indexing API (allowing you to hook your custom content types with 
   through Zope 3 adapters).

Changes since V 3.0.2:

   - multi-field query support added: the query parser now accepts queries 
where you can search within
     multiple fields using a single query e.g. 'title::phrase(The Zope 
Book) and author::or(michel amos)'
     which searches for all documents with the exact title 'The Zope Book' 
and where the author field
     contains 'michel' or 'amos'. See doc/README.txt for details on the 
query syntax.

   - new extension module 'txngstemmer' providing language dependant 
stemmer support based on the Snowball
     stemmer library. This is a reimplementation of the older PyStemmer 
extension module based on the
     new Snowball reimplementation allowing a much cleaner and easier 
integration. Outstanding compilation
     problems and problems with unicode should be finally resolved. Stemmer 
support will be added to TextIndexNG
     in a later version.


  - Zope 2.8 or Zope 2.7 (+ Five) or Zope 3 (Zope 3 has nothing like 
catalogs yet)

  TextIndexNG V3 will *not* run with bare Zope 2.7 installations without 
  (and this will not be changed in the future).



For installation and documentation issues refer to doc/README.txt from the 
It's basically the same procedure as with former versions except you *need* 
recompile the extension modules. Windows binaries of the required extension 
are currently not available (any volunteers?).

TextIndexNG V 3 is published under the GPL.
