Interface IMatchBoolPrefixQuery

A match_bool_prefix query analyzes its input and constructs a bool query from the terms. Each term except the last is used in a term query. The last term is used in a prefix query.

Fuzziness

Allows fuzzy matching based on the type of field being queried. Applies only to the term sub queries constructed, and not the prefix query for the final term.

Declaration
[DataMember(Name = "fuzziness")]
IFuzziness Fuzziness { get; set; }
Property Value
Type Description
IFuzziness

FuzzyRewrite

Controls how the query is rewritten if Fuzziness is set. In this scenario, the default is TopTermsBlendedFreqs(int). Applies only to the term sub queries constructed, and not the prefix query for the final term.

Declaration
[DataMember(Name = "fuzzy_rewrite")]
MultiTermQueryRewrite FuzzyRewrite { get; set; }
Property Value
Type Description
MultiTermQueryRewrite

FuzzyTranspositions

Sets whether transpositions are supported in fuzzy queries.

The default metric used by fuzzy queries to determine a match is the Damerau-Levenshtein distance formula which supports transpositions. Setting transposition to false will switch to classic Levenshtein distance. If not set, Damerau-Levenshtein distance metric will be used. Applies only to the term sub queries constructed, and not the prefix query for the final term.
Declaration
[DataMember(Name = "fuzzy_transpositions")]
bool? FuzzyTranspositions { get; set; }
Property Value
Type Description
bool?

MaxExpansions

Controls the number of terms fuzzy queries will expand to. Defaults to 50. Applies only to the term sub queries constructed, and not the prefix query for the final term.

Declaration
[DataMember(Name = "max_expansions")]
int? MaxExpansions { get; set; }
Property Value
Type Description
int?

Declaration
[DataMember(Name = "minimum_should_match")]
MinimumShouldMatch MinimumShouldMatch { get; set; }
Property Value
Type Description
