Hi,
by default each Jahia instance do index and search in a separate index file. But you can configure each of them to :
1) only search but no perform indexation 2) to use a common search index
These settings are done in the web.xml file of each Jahia instance.
<init-param>
<param-name>org.apache.lucene.searchIndexRootDir</param-name>
<!-- to point to a common search index ( but only one Jahia instance should run indexation -->
<param-value>/WEB-INF/var/search_indexes</param-value>
</init-param>
<init-param>
<param-name>org.apache.lucene.localIndexing</param-name>
<param-value>1</param-value> <!-- 1: allow local indexing, 0: do not index -->
</init-param>
we've managed to refactor the search service in near future.

Subject: question about search indexes and clusters
Hi everyone,
I'm currently setting up Jahia in a cluster environment with 2 Jahia servers.
I need failover support in my architecture. Thus I need to have data duplicated on both servers.
I'm thinking about implementing a mechanism to notify and synchronize the other machine and vice
versa, especially for the Jahia files (Big Text, PDFs etc...)
But what about the search indexes?
I'm a little nervous about synchronizing index files.
I'm thinking about this scenario:
Since indexing a file (PDF) can take some time, if user1 indexes a PDF on server1 and user2
idnexes a PDF on server2 almost at the same time, then index files could be overriden one with the
other during synchronisation.
I've read the Jahia Clustering HowTo. They talk about only having one Jahia instance for indexing,
ut how do you implement this? (do you configure with the Lucene config files ?)
Thanks again for any help about clustering Gilles
