How do I...Configure Lucene in a Clustered Environment

NOTE: This requires Deki Wiki 8.05 (Jay Cooke) or greater.

If you're running Deki Wiki in a clustered environment, you'll want to configure the Lucene service to run as a service on one of the nodes in the cluster.  Follow these instructions to configure lucene to run as a remote service.

Add the following to your mindtouch.deki.startup.xml to initialize the service

 <action verb="POST" path="/host/services">
   <config>         
     <path>deki/luceneindex</path>
     <sid>sid://mindtouch.com/2007/06/luceneindex</sid>
     <path.store>/var/www/dekiwiki/bin/cache/luceneindex/$1</path.store>
     <apikey>your_api_key</apikey>
   </config>
 </action>

Edit the <indexer> section of your mindtouch.deki.startup.xml to use the remote service:

<indexer src="http://dekiwiki:8081/deki/luceneindex?apikey=your_api_key">
  <filter-path extension="doc">/var/www/dekiwiki/bin/filters/wvText</filter-path>
  <filter-path extension="pdf">/var/www/dekiwiki/bin/filters/pdf2text</filter-path>
  <filter-path extension="xhtml">/var/www/dekiwiki/bin/filters/html2text</filter-path>
  <!-- SNIP -->
</indexer>

The uri in the src attribute tells Deki Wiki where the Lucene Index is running and where index updates will be POSTed to.
