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
TextIndexNG
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.
Requirements:
- 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
Five
(and this will not be changed in the future).
Download:
http://sf.net/projects/textindexng
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 GPL.
