Subject Re: Want to Delete Existing Index & create fresh index
Date Sat, 14 May 2011 17:23:57 GMT
Note that you should only delete the 'index' directory, not the 'data' directory as well. Also
just deleting the files in the 'index' directory will not work either.

You should also check the startup log for solr/lucene, usually any issues are logged there.
