Create a CustomScoreQuery over input subQuery.

Create a CustomScoreQuery over input subQuery and a {@link ValueSourceQuery}.

Create a CustomScoreQuery over input subQuery and a {@link ValueSourceQuery}.

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.

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}.

Compute a custom score by the subQuery score and the ValueSourceQuery score.

Compute a custom score by the subQuery score and a number of ValueSourceQuery scores.

Please override {@link #getCustomScoreProvider} and return a subclass of {@link CustomScoreProvider} for the given {@link IndexReader}. see CustomScoreProvider#customScore(int,float,float[])

Returns true if

CopyC#

o

is equal to this.

Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.

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.

Returns a hash code value for this object.

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.

Gets the Type of the current instance.

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.

Creates a shallow copy of the current Object.

A short name of this query, used in {@link #ToString(String)}.

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

.

Set the strict mode of this query.

Prints a query to a string.

Expert: Constructs and initializes a Weight for a top-level query.
