Try search repeatedly and report results

To test the hypothesis that something is going
wrong with the indexing itself, we're repeating
just the search multiple times to see what is
returned. If the search fails every time for each
of the 10 loop iterations, then the object has
not been indexed at all. If only the first search
is failing, then a small wait may be necessary.
This could be caused by the 2 different processes
(blitz's `IUpdate.indexObject()` invocation and
the background indexer) contending for the Document.
