Use the IndexSearcher class to perform search queries against an index. (For searching multiple indexes at once, see PolySearcher).
IndexSearchers operate against a single point-in-time view or Snapshot of the index. If an index is modified, a new IndexSearcher must be opened to access the changes.

my $int = $index_searcher->doc_freq( field => $field # required term => $term # required );
Return the number of documents which contain the term in the given field.
$index_searcher->collect( query => $query # required collector => $collector # required );
