SpanQuery Methods

The methods of the SpanQuery class are listed below. For a complete list of SpanQuery class members, see the SpanQuery Members topic.

Public Instance Methods

Clone (inherited from Query)Returns a clone of this query.
Combine (inherited from Query)Expert: called when re-writing queries under MultiSearcher. Create a single query suitable for use by all subsearchers (in 1-1 correspondence with queries). This is an optimization of the OR of all queries. We handle the common optimization cases of equal queries and overlapping clauses of boolean OR queries (as generated by MultiTermQuery.rewrite() and RangeQuery.rewrite()). Be careful overriding this method as queries[0] determines which method will be called and is not necessarily of the same type as the other queries.
CreateWeight_ForNUnitTest 
Equals (inherited from Object)Determines whether the specified Object is equal to the current Object.
ExtractTerms (inherited from Query) Expert: adds all terms occuring in this query to the terms set. Only works if this query is in its {@link #rewrite rewritten} form.
GetBoost (inherited from Query)Gets the boost for this clause. Documents matching this clause will (in addition to the normal weightings) have their score multiplied by
b
. The boost is 1.0 by default.
GetFieldReturns the name of the field matched by this query.
GetHashCode (inherited from Object)Serves as a hash function for a particular type. GetHashCode is suitable for use in hashing algorithms and data structures like a hash table.
GetPayloadSpans Returns the matches for this query in an index, including access to any payloads at thos positions. Implementin classes that want access to the payloads will need to implement this. WARNING: The status of the Payloads feature is experimental. The APIs introduced here might change in the future and will not be supported anymore in such a cse.
GetSimilarity (inherited from Query)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.
GetSpansExpert: Returns the matches for this query in an index. Used internally to search for spans.
GetTermsReturns a collection of all terms matched by this query.
GetType (inherited from Object)Gets the Type of the current instance.
Rewrite (inherited from Query)Expert: called to re-write queries into primitive queries. For example, a PrefixQuery will be rewritten into a BooleanQuery that consists of TermQuerys.
SetBoost (inherited from Query)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
.
ToString (inherited from Query)Overloaded. Prints a query to a string.
Weight (inherited from Query)Expert: Constructs and initializes a Weight for a top-level query.

Protected Instance Methods

Finalize (inherited from Object)Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.
MemberwiseClone (inherited from Object)Creates a shallow copy of the current Object.
