I am pleased to announce the first alpha release of TextIndexNG V 1.0.

TextIndexNG is a pluggable index for the ZCatalog that enhances the full
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

    * optional 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


    * Zope 2.5 or Zope CVS trunk checkout


    * http://www.zope.org/Members/ajung/TextIndexNG/wiki


    * http://www.zope.org/Members/ajung/TextIndexNG/


    * The installation is described in the Wiki (see above)

Changes sind alpha 1:

    * complete Registry implementation rewritten. Interfaces for pluggable
components are strictly enforced.

    * every pluggable component resides now in a registry

    * broken similarity search fixed

    * additional options for interactiveDemo.py

    * integrated Matt Hamiltons compressed lists code

    * changed license of TextIndexNG to ZPL

    * the queryparser extension module should now build out-of-the-box at
least on all Unix
      plattforms (flex, bison required).

    * minor code cleanup and speedup in the extension modules
