[Zope] [ANN] TextIndexNG 3.1.9 released

[Andreas Jung]

I am pleased to announce the release of TextIndexNG V 3.1.9.

TextIndexNG V 3 is a complete new implementation based on Zope 3 
technologies and can be used both in Zope 2.8 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
   TextIndexNG through Zope 3 adapters).


Changes in V 3.1.9:

   - added explicit check for the existence of the extension module so
     TextIndexNG3
     will now fail at startup time with an exception instead of failing
     when creating new index instances

   - added UI support for valid word separators

   - added IObjectWrapper interface to core indexer engine to provide
     generic support   for objects wrapped into some kind of wrapper. The
     purpose of the interface is to
     attach IObjectWrapper to wrapper classes using five:implements without
     having  the need to modify exisiting code.

   - added support to deal better with indexing CMF content where the
     content object  is wrapped inside a
     CMFCore.CatalogTool.IndexableObjectWrapper instance.
     TextIndexNG3/adapters/configure.zcml contains some commented
     configurations to attach a marker interface to IndexableObjectWrapper
     and in an addition an adapter  to extract the wrapped object without
     having the need to add some CMF knowledge to the core indexing engine

   - added IExtensibleIndexableObjectWrapper for better integration with
     Plone (whose CatalogTool wraps Plone objects as
     ExtensibleIndexableObjectWrapper instances)

   - optimized internal datastructures (existing indexes should be
     cleared and reindexed)


Requirements:

  - Zope 2.8+, Zope 3.2+

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

TextIndexNG V 3 is published under the ZPL.
