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.

Declaration
public bool? FuzzyTranspositions { get; set; }
Property Value
Type Description
bool?

Lenient

public bool? Lenient { get; set; }
Property Value
Type Description

ZeroTermsQuery

If the analyzer used removes all tokens in a query like a stop filter does, the default behavior is to match no documents at all. In order to change that, ZeroTermsQuery can be used, which accepts None (default) and All which corresponds to a match_all query.

Declaration
public ZeroTermsQuery? ZeroTermsQuery { get; set; }
Property Value
Type Description
ZeroTermsQuery?
