> NearSpansOrdered's constructor will throw an IllegalArgumentException
> if less than 2 clauses are given, while NearSpansOrdered won't.
> On the other hand, SpanNearQuery accepts less than 2 clauses and has explicit optimization for 0-caluse and 1-clause queries in getSpans() method.
> So, should SpanNearQuery accept less than 2 clauses or not?
