    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.

    Analyzer

    The analyzer to use for the query

    Declaration
    [DataMember(Name = "analyzer")]
    string Analyzer { get; set; }
    Property Value
    Type Description
    string

    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?

    MinimumShouldMatch

    A value controlling how many "should" clauses in the resulting boolean query should match. It can be an absolute value, a percentage or a combination of both. Applies to the bool query constructed.

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

    Operator

    The operator used if no explicit operator is specified. The default operator is Or. Applies to the bool query constructed.

    Declaration
    [DataMember(Name = "operator")]
    Operator? Operator { get; set; }
    Property Value
    Type Description
    Operator?

    PrefixLength

    Set the prefix length for fuzzy queries. Default is 0. Applies only to the term sub queries constructed, and not the prefix query for the final term.

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

    Declaration
    [DataMember(Name = "query")]
    string Query { get; set; }
    Property Value
    Type Description
