Hi all,
 I'm wondering what's the best way to completely change a big index
without loosing any requests.
 That's how I do at the moment:

 solr index is a soft link to a directory dir.
 When I want to install a new index (in dir.new), I do a

 mv dir dir.old ; mv dir.new dir
 Then I ask for a reload of the solr application (within tomcat).

 I can see two problems with this method:

  - Between the two mv's, the directory dir does not exists, which can
cause some solr failure.

  - Apparently It's not that safe to reload a webapp within tomcat.
   I thought it was the equivalent of the apache graceful reloading
(completing current requests and putting incoming ones into a queue
while the application restarts), but it's   apparently not. I noticed
we have a couple of query lost when it happens.
 One is a 503 This application is not currently available, and the one
just after is
 a 404 /solr//select/ - The requested resource (/solr//select/) is not
available.

 Does anybody know how to avoid this behaviour, and eventually what is
the best way to swap between two big indexes.

Thanks for any help !

Jerome.
