When I first read this, I thought you meant that you'd lost all Solr indexes for _all_ Authorizables or _all_ Content. But you just mean that _individual_ records are missing from the index, right?
If so, yes, I've seen the behavior plenty of times, and the cause is over-panicky error handling in our Solr integration code. Virtually all Solr indexing is done via a SparseMapContent event listener which places the event on an indexing queue manager, which in turn delivers the event to an index handler. The handlers tend to send any exceptions on up the stack, and the queue managers have tended to drop the event like a hot potato, never picking it back up again. When that happens, the new or replaced data isn't indexed. (Or, on events which should have led to deletion, the obsolete index continues to hang around.) See: https://jira.sakaiproject.org/browse/SOLR-36 http://collab.sakaiproject.org/pipermail/oae-dev/2012-January/001061.html As I and others add bug reports and fixes, indexing should get more stable over time. That said, periodic full re-indexing is likely to remain part of dev-ops life for the foreseeable future.
