> The ParallelMultiSearcher doesn't allow non-IOException exceptions to be
> managed by the calling application.
> LUCENENET-388 worked around one specific example of this, but any genuine
> Lucene exception (eg: BooleanQuery.TooManyClauses) will also fall foul of
> this pattern.
> In our specific instance we could treat the symptoms and up the max clause
> count, but I'm sure there will be more. Could the System.IOException be
> generalised to System.Exception? Or would that be too much deviation from
> the Java code base?
