The CustomScoreQuery type exposes the following members.

Constructors

  NameDescription
Public methodCustomScoreQuery(Query)
Create a CustomScoreQuery over input subQuery.
Public methodCustomScoreQuery(Query, ValueSourceQuery)
Create a CustomScoreQuery over input subQuery and a {@link ValueSourceQuery}.
Public methodCustomScoreQuery(Query, array<ValueSourceQuery>[]()[][])
Create a CustomScoreQuery over input subQuery and a {@link ValueSourceQuery}.

Methods

  NameDescription
Public methodClone (Overrides Query..::..Clone()()()().)
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 (Overrides Query..::..CreateWeight(Searcher).)
Public methodCustomExplain(Int32, Explanation, Explanation) Obsolete.
Explain the custom score. The doc is relative to the current reader, which is unknown to CustomScoreQuery when using per-segment search (since Lucene 2.9). Please override {@link #getCustomScoreProvider} and return a subclass of {@link CustomScoreProvider} for the given {@link IndexReader}.
Public methodCustomExplain(Int32, Explanation, array<Explanation>[]()[][]) Obsolete.
Explain the custom score. The doc is relative to the current reader, which is unknown to CustomScoreQuery when using per-segment search (since Lucene 2.9). Please override {@link #getCustomScoreProvider} and return a subclass of {@link CustomScoreProvider} for the given {@link IndexReader}.
Public methodCustomScore(Int32, Single, Single) Obsolete.
Compute a custom score by the subQuery score and the ValueSourceQuery score. The doc is relative to the current reader, which is unknown to CustomScoreQuery when using per-segment search (since Lucene 2.9). Please override {@link #getCustomScoreProvider} and return a subclass of {@link CustomScoreProvider} for the given {@link IndexReader}. @see CustomScoreProvider#customScore(int,float,float)
Public methodCustomScore(Int32, Single, array<Single>[]()[][]) Obsolete.
Compute a custom score by the subQuery score and a number of ValueSourceQuery scores. The doc is relative to the current reader, which is unknown to CustomScoreQuery when using per-segment search (since Lucene 2.9). Please override {@link #getCustomScoreProvider} and return a subclass of {@link CustomScoreProvider} for the given {@link IndexReader}. see CustomScoreProvider#customScore(int,float,float[])
Public methodEquals
Returns true if
CopyC#
o
is equal to this.
(Overrides Query..::..Equals(Object).)
Public methodExtractTerms (Overrides Query..::..ExtractTerms(Hashtable).)
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.)
Protected methodGetCustomScoreProvider
Public methodGetHashCode
Returns a hash code value for this object.
(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.)
Public methodIsStrict
Checks if this is strict custom scoring. In strict custom scoring, the ValueSource part does not participate in weight normalization. This may be useful when one wants full control over how scores are modified, and does not care about normalizing by the ValueSource part. One particular case where this is useful if for testing this query.

Note: only has effect when the ValueSource part is not null.

Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Public methodName
A short name of this query, used in {@link #ToString(String)}.
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 methodSetStrict
Set the strict mode of this 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.)
