+/**
+ * Just counts the total number of hits. For cases when this is the only
collector used, {@link
+ * IndexSearcher#count(Query)} should be called instead of {@link
IndexSearcher#search(Query,
+ * Collector)} as the former is faster whenever the match can be returned
directly from the index
Review comment:
I meant match count, but count is fine too.
