Local search indexing in Jahia cluster

Hello,

I am experiencing a problem with the search index in the cluster 
environment.
I have two nodes in a cluster. Each of them is configured to use local 
indexing.

I create some content on one of the nodes, say node1, and it is properly 
replicated to node2.
But the search index is only properly updated on the node1, but not on the 
second one.

I will try to set up another scenario, where the indexing is performed 
only on one node and the index folder is shared among two instances.


I would like to know, if anyone has any experience with Jahia clustering, 
which scenarios were used for search indexing and were there any problems?

Thanks to all in advance!

Sergiy.
