You could use getSpans() on the top level SpanQuery, and use a loop calling next() on the Spans, and ignore duplicate doc() values from the Spans in that loop. A counter in the loop would also give you the number of matching occurrences of the SpanQuery. This way of using the Spans directly should be slightly more efficient than using a HitCollector, but don't hold your breath. In case you have ordered SpanQuery's without overlaps, the NearSpansOrdered here might be a bit faster than the NearSpans currently in Lucene: http://issues.apache.org/jira/browse/LUCENE-413 (you'll also need the patch to SpanNearQuery).
