Subject Re: Solr is deleting newly created index from index folder
Date Wed, 20 Nov 2013 12:41:34 GMT
I cannot imagine that Solr suddenly starts deleting indexes without you
changing anything, although all things are possible. Sanity check:
do you have at least as much free space on your disk as the total size
of your index on disk?

Your query will delete everything from your index with an endtime, except
some very specific dates (i.e. a Unix time of 0).

First thing I'd do is stop the cron job to see if that fixes your problem.
bet is that this query is not doing what you expect.

Then submit the query to Solr from a URL or from the admin page, turn
query debugging on and examine the results. Do this with just the query,
not the delete parts, i.e.
q=(endtime:[* TO NOW] AND -endtime:"1970-01-01T01:00:00Z")

BTW, the AND is unnecessary, but I don't think that's relevant anyway...

If that doesn't show the problem, please show us the results of running
the query with debug info so we see the parsed query.
