Called once for every document matching a query, with the unbased document number.

Note: This is called in an inner search loop. For good search performance, implementations of this method should not call {@link Searcher#Doc(int)} or {@link Lucene.Net.Index.IndexReader#Document(int)} on every hit. Doing so can slow searches by an order of magnitude or more.

Creates a new {@link TopScoreDocCollector} given the number of hits to collect and whether documents are scored in order by the input {@link Scorer} to {@link #SetScorer(Scorer)}.

NOTE: The instances returned by this method pre-allocate a full array of length

, and fill the array with sentinel objects.

Determines whether the specified Object is equal to the current Object.

Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.

Serves as a hash function for a particular type.

The total number of documents that matched this query.

Gets the Type of the current instance.

Creates a shallow copy of the current Object.

Populates the results array with the ScoreDoc instaces. This can be overridden in case a different ScoreDoc type should be returned.

Returns the top docs that were collected by this collector.

Returns the documents in the rage [start .. pq.size()) that were collected by this collector. Note that if start >= pq.size(), an empty TopDocs is returned.
This method is convenient to call if the application allways asks for the last results, starting from the last 'page'.
NOTE: you cannot call this method more than once for each search execution. If you need to call it more than once, passing each time a different

start

, you should call {@link #TopDocs()} and work with the returned {@link TopDocs} object, which will contain all the results this search execution collected.

Returns the documents in the rage [start .. start+howMany) that were collected by this collector. Note that if start >= pq.size(), an empty TopDocs is returned, and if pq.size() - start < howMany, then only the available documents in [start .. pq.size()) are returned.
This method is useful to call in case pagination of search results is allowed by the search application, as well as it attempts to optimize the memory used by allocating only as much as requested by howMany.
NOTE: you cannot call this method more than once for each search execution. If you need to call it more than once, passing each time a different range, you should call {@link #TopDocs()} and work with the returned {@link TopDocs} object, which will contain all the results this search execution collected.

Returns a String that represents the current Object.

The priority queue which holds the top documents. Note that different implementations of PriorityQueue give different meaning to 'top documents'. HitQueue for example aggregates the top scoring documents, while other PQ implementations may hold documents sorted by other criteria.

The total number of documents that the collector encountered.
