Subject RE: Shared index base
Date Tue, 26 Feb 2008 18:22:12 GMT
How do you handle commits to the index? By that, I mean that Solr
recreates its searcher when you issue a commit, but only for the system
that does the commit. Wouldn't you be left with searchers on the other
machines that are stale?

I hope so. I've found that every once in a while Solr 1.2 replication  
will die, from a temp-index.... file that seems to ham it up. Removing  
that file on all the servers fixes the issue though.

We'd like to be able to point all the servers at an NFS location for  
their index files, and use a single server to update it.
