The BoostingQuery type exposes the following members.

Methods

  NameDescription
Public methodClone
Returns a clone of this query.
(Inherited from Query.)
Public methodCombine
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()). 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.
(Inherited from Query.)
Public methodCreateWeight
Expert: Constructs an appropriate Weight implementation for this query.

Only implemented by primitive queries, which re-write to themselves.

(Inherited from Query.)
Public methodEquals (Overrides Query..::..Equals(Object).)
Public methodExtractTerms
Expert: adds all terms occuring in this query to the terms set. Only works if this query is in its {@link #rewrite rewritten} form.
(Inherited from Query.)
Protected methodFinalize
Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.
(Inherited from Object.)
Public methodGetBoost
Gets the boost for this clause. Documents matching this clause will (in addition to the normal weightings) have their score multiplied by
CopyC#
b
. The boost is 1.0 by default.
(Inherited from Query.)
Public methodGetHashCode (Overrides Query..::..GetHashCode()()()().)
Public methodGetSimilarity
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.
(Inherited from Query.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Public methodRewrite (Overrides Query..::..Rewrite(IndexReader).)
Public methodSetBoost
Sets the boost for this query clause to
CopyC#
b
. Documents matching this clause will (in addition to the normal weightings) have their score multiplied by
CopyC#
b
.
(Inherited from Query.)
Public methodToString()()()()
Prints a query to a string.
(Inherited from Query.)
Public methodToString(String) (Overrides Query..::..ToString(String).)
Public methodWeight
Expert: Constructs and initializes a Weight for a top-level query.
(Inherited from Query.)
