The CustomScoreQuery type exposes the following members.
Methods
| Name | Description | |
|---|---|---|
 | Clone | (Overrides Query..::..Clone()()()().) |
| Combine | 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.) |
| CreateWeight | (Overrides Query..::..CreateWeight(Searcher).) |
| CustomExplain(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}.
|
| CustomExplain(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}.
|
| CustomScore(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)
|
| CustomScore(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}.

|
| Equals | Returns true if (Overrides Query..::..Equals(Object).) CopyC#o |
| ExtractTerms | (Overrides Query..::..ExtractTerms(Hashtable).) |
 | Finalize | Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
| GetBoost | Gets the boost for this clause. Documents matching
this clause will (in addition to the normal weightings) have their score
multiplied by (Inherited from Query.)CopyC#b |
| GetCustomScoreProvider | |
| GetHashCode | Returns a hash code value for this object. (Overrides Query..::..GetHashCode()()()().) |
| GetSimilarity | 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.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| IsStrict | 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.
|
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| Name | A short name of this query, used in {@link #ToString(String)}. |
| Rewrite | (Overrides Query..::..Rewrite(IndexReader).) |
| SetBoost | Sets the boost for this query clause to (Inherited from Query.)CopyC#b CopyC#b |
| SetStrict | Set the strict mode of this query. |
| ToString()()()() | Prints a query to a string. (Inherited from Query.) |
| ToString(String) | (Overrides Query..::..ToString(String).) |
| Weight | Expert: Constructs and initializes a Weight for a top-level query. (Inherited from Query.) |
