Searchable
HitCollector.collect(int,float)
is called for every non-zero
scoring document.
HitCollector-based access to remote indexes is discouraged.
Applications should only use this if they need all of the
matching documents. The high-level search API (Searcher.search(Query)
) is usually more efficient, as it skips
non-high-scoring hits.

This is intended to be used in developing Similarity implementations, and, for good performance, should not be displayed with every hit. Computing an explanation is as expensive as executing the query over the entire index.
Applications should call Searcher.explain(Query, int)
.
