Public Member Functions
	SpanOrQuery (params SpanQuery[] clauses)
	Construct a SpanOrQuery merging the provided clauses.
virtual SpanQuery[]	GetClauses ()
	Return the clauses whose spans are matched.
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.Object	Clone ()
	Returns a clone of this query.
override 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.
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 bool	Equals (System.Object o)
override int	GetHashCode ()
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	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.
override int	GetHashCode ()
override bool	Equals (System.Object obj)

Properties
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.
