I am pleased to announce the first "technical preview" release of
TextIndexNG is a pluggable index for the ZCatalog that enhances the full
indexing capabilities of Zope by providing the following features:

  - stemmer support for 12 languages

  - similarity search (soundex, metaphone support)
    (not fully integrated)

  - NEAR search (including phrase search)

  - new query parser

  - extended stop word support

  - Thesauri (planned)

  - word normalization

  - unicode support

  - new 'test' tab for interactive testing

This version is for development purposes only. Most features are already
working (with some limitations). The query parser is somewhat limited and
requires some more work to provide a clean query language (any volunteers ?


  TextIndexNG currently runs only on the Zope trunk but not
  with Zope 2.5.X (some tweaks are required to install it
  under 2.5.X)

(Limited) documentation is available from:


The sources of TextIndex are available from:


   The installation is described in the Wiki (see above)
