Apache Solr Content Extraction Library (Solr Cell)
Release Notes
This file describes changes to the Solr Cell (contrib/extraction) module. See SOLR-284 for details.
Introduction
------------
Apache Solr Extraction provides a means for extracting and indexing content contained in "rich" documents, such
as Microsoft Word, Adobe PDF, etc. (Each name is a trademark of their respective owners) This contrib module
uses Apache Tika to extract content and metadata from the files, which can then be indexed. For more information,
see http://wiki.apache.org/solr/ExtractingRequestHandler
Getting Started
---------------
You will need Solr up and running. Then, simply add the extraction JAR file, plus the Tika dependencies (in the ./lib folder)
to your Solr Home lib directory. See http://wiki.apache.org/solr/ExtractingRequestHandler for more details on hooking it in
and configuring.
