ConstantScore

A rewrite method that performs like constant_score_boolean when there are few matching terms and otherwise visits all matching terms in sequence and marks documents for that term. Matching documents are assigned a constant score equal to the query’s boost.

Declaration
public static MultiTermQueryRewrite ConstantScore { get; }
Property Value
Type Description
MultiTermQueryRewrite

ConstantScoreBoolean

Similar to scoring_boolean except scores are not computed. Instead, each matching document receives a constant score equal to the query’s boost. This rewrite method will hit too many clauses failure if it exceeds the boolean query limit (defaults to 1024).

Declaration
public static MultiTermQueryRewrite ConstantScoreBoolean { get; }
Property Value
Type Description
MultiTermQueryRewrite

Rewrite

The type of multi term rewrite to perform

public RewriteMultiTerm Rewrite { get; }
Property Value

ScoringBoolean

A rewrite method that first translates each term into a should clause in a boolean query, and keeps the scores as computed by the query. Note that typically such scores are meaningless to the user, and require non-trivial CPU to compute. This rewrite method will hit too many clauses failure if it exceeds the boolean query limit (defaults to 1024).

Declaration
public static MultiTermQueryRewrite ScoringBoolean { get; }
Property Value
Type Description
MultiTermQueryRewrite

Size

The size of the top scoring terms to use

Declaration
public int? Size { get; }
Property Value
Type Description
int?

TopTerms(int)

A rewrite method that first translates each term into should clause in boolean query, and keeps the scores as computed by the query. This rewrite method only uses the top scoring terms so it will not overflow boolean max clause count.

controls the size of the top scoring terms to use.
Declaration
public static MultiTermQueryRewrite TopTerms(int size)
Parameters
Type Name Description
int size
Returns
Type Description
MultiTermQueryRewrite

TopTermsBlendedFreqs(int)

A rewrite method that first translates each term into should clause in boolean query, but all term queries compute scores as if they had the same frequency. In practice the frequency which is used is the maximum frequency of all matching terms. This rewrite method only uses the top scoring terms so it will not overflow boolean max clause count.

controls the size of the top scoring terms to use.
Declaration
public static MultiTermQueryRewrite TopTermsBlendedFreqs(int size)
Parameters
Type Name Description
int size
Returns
Type Description

TopTermsBoost(int)

A rewrite method that first translates each term into should clause in boolean query, but the scores are only computed as the boost. This rewrite method only uses the top scoring terms so it will not overflow the boolean max clause count.

controls the size of the top scoring terms to use.
Declaration
public static MultiTermQueryRewrite TopTermsBoost(int size)
Parameters
Type Name Description
int size
Returns
Type Description
MultiTermQueryRewrite
