Public Member Functions

 SpanTermQuery (Term term)
 Construct a SpanTermQuery matching the named term's spans.
 
override void ExtractTerms (System.Collections.Generic.ISet< Term > terms)
 Expert: adds all terms occuring in this query to the terms set. Only works if this query is in its rewritten form.
 
override System.String ToString (System.String field)
 Prints a query to a string, with field assumed to be the default field and omitted. The representation used is one that is supposed to be readable by QueryParser. However, there are the following limitations:

  • If the query was created by the parser, the printed representation may not be exactly what was parsed. For example, characters that need to be escaped will be represented without the required backslash.
  • Some of the more complicated queries (e.g. span queries) don't have a representation that can be parsed by QueryParser.

 
override int GetHashCode ()
 
override bool Equals (System.Object obj)
 
override Spans GetSpans (IndexReader reader)
 Expert: Returns the matches for this query in an index. Used internally to search for spans.
 
- Public Member Functions inherited from Lucene.Net.Search.Spans.SpanQuery
override Weight CreateWeight (Searcher searcher)
 Expert: Constructs an appropriate Weight implementation for this query.
 
- Public Member Functions inherited from Lucene.Net.Search.Query
override System.String ToString ()
 Prints a query to a string.
 
virtual Weight Weight (Searcher searcher)
 Expert: Constructs and initializes a Weight for a top-level query.
 
virtual Query Rewrite (IndexReader reader)
 Expert: called to re-write queries into primitive queries. For example, a PrefixQuery will be rewritten into a BooleanQuery that consists of TermQuerys.
 
virtual Query Combine (Query[] queries)
 Expert: called when re-writing queries under MultiSearcher.
 
virtual Similarity GetSimilarity (Searcher searcher)
 Expert: Returns the Similarity implementation to be used for this query. Subclasses may override this method to specify their own Similarity implementation, perhaps one that delegates through that of the Searcher. By default the Searcher's Similarity implementation is returned.
 
virtual System.Object Clone ()
 Returns a clone of this query.
 
override int GetHashCode ()
 
override bool Equals (System.Object obj)
 

Properties

virtual Term Term [get]
 Return the term whose spans are matched.
 
override string Field [get]
 
- Properties inherited from Lucene.Net.Search.Spans.SpanQuery
abstract string Field [get]
 Returns the name of the field matched by this query.
 
- Properties inherited from Lucene.Net.Search.Query
virtual float Boost [get, set]
 Gets or sets the boost for this query clause to b. Documents matching this clause will (in addition to the normal weightings) have their score multiplied by b. The boost is 1.0 by default.
 

Additional Inherited Members

- Static Public Member Functions inherited from Lucene.Net.Search.Query
static Query MergeBooleanQueries (params BooleanQuery[] queries)
 Expert: merges the clauses of a set of BooleanQuery's into a single BooleanQuery.
