This lucene based plugin provides all the power of Lucene with eZ publish. Although it is in an beta state, it works very well in our test environment and live production sites.

FEATURES
=========

- all of lucene, see http://lucene.apache.org/java/docs/queryparsersyntax.html, including boolean searches, range searches, fuzzy searches, wildcards, ...
- full implementation of eZ publish permission system (roles/policies)
- full use of eZ publish rich object model which is mapped to lucene "docs and fields"
- possibility to search on meta data like owner name (!)
- enhanced templates showing relevance
- custom boosting of classes, attributes and even datatypes to tune the search engine to your particular setup
- very fast searching and index updates
- "more like this" functionality (/lucene/similar/<nodeid>) (!)
- full support of advanced search
- support for sorting when called with fetch function

INSTALL
======
Brief installation instructions are provided in the README file
Important: configure your site with delayed indexing

UPGRADE
========

- From 0.2 to 0.7
+ due to the changes in meta-data fields, you will have to re-index your ezp site again with the provided script in extension/lucene/bin/php
+ take a look at the templates, you may need to adapt your own search templates


FUTURE
=======

A lot more, see the summer conference talk and updates here later as well as the ROADMAP file in the distribution:

- sorting in advanced search and in template fetch (content, search) [partially implemented]
- integrating image query by example (based on image features texture, color histogram, color distribution) [not released, but first versions work locally]
- search stats (are already collected, but no interface for viewing them)
- more robustness

BUGS
=====

- please report them :-)

IMPORTANT


 

You should configure ez publish with delayed indexing and make sure multiple updates do not run in parallel. If not, your search index may become corrupt!
