C# Класс Lucene.Net.Search.Searcher

creates a weight for query

Returns an Explanation that describes how doc scored against query.

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.

Finds the top n hits for query, applying filter if non-null.

Finds the top n hits for query.

Search implementation with arbitrary sorting. Finds the top n hits for query, applying filter if non-null, and sorting the hits by the criteria in sort.

NOTE: this does not compute scores by default; use IndexSearcher.SetDefaultFieldSortScoring(bool,bool) to enable scoring.

Lower-level search API.

Collector.Collect(int) is called for every matching document.

Applications should only use this if they need all of the matching documents. The high-level search API (Searcher.Search(Query, int) ) is usually more efficient, as it skips non-high-scoring hits.

Note: The score passed to this method is a raw score. In other words, the score will not necessarily be a float whose value is between 0 and 1.

Lower-level search API.

Collector.Collect(int) is called for every matching document.
Collector-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, Filter, int)) is usually more efficient, as it skips non-high-scoring hits.
