Multi Match Usage
editMulti Match Usage
editFluent DSL example
editq .MultiMatch(c => c .Fields(f => f.Field(p=>p.Description).Field("myOtherField")) .Query("hello world") .Analyzer("standard") .Boost(1.1) .Slop(2) .Fuzziness(Fuzziness.Auto) .PrefixLength(2) .MaxExpansions(2) .Operator(Operator.Or) .MinimumShouldMatch(2) .FuzzyRewrite(MultiTermQueryRewrite.ConstantScoreBoolean) .TieBreaker(1.1) .CutoffFrequency(0.001) .Lenient() .ZeroTermsQuery(ZeroTermsQuery.All) .Name("named_query") )
Object Initializer syntax example
editnew MultiMatchQuery { Fields = Field<Project>(p=>p.Description).And("myOtherField"), Query = "hello world", Analyzer = "standard", Boost = 1.1, Slop = 2, Fuzziness = Fuzziness.Auto, PrefixLength = 2, MaxExpansions = 2, Operator = Operator.Or, MinimumShouldMatch = 2, FuzzyMultiTermQueryRewrite = MultiTermQueryRewrite.ConstantScoreBoolean, TieBreaker = 1.1, CutoffFrequency = 0.001, Lenient = true, ZeroTermsQuery = ZeroTermsQuery.All, Name = "named_query", }
Example json output.

Multi match with boost usage
editFluent DSL example
editq .MultiMatch(c => c //.Fields(f => f.Field(p=>p.Description, 2.2).Field("myOtherField^0.3")) .Fields(Field<Project>(p=>p.Description, 2.2).And("myOtherField^0.3")) .Query("hello world") )
Object Initializer syntax example
editnew MultiMatchQuery { Fields = Field<Project>(p=>p.Description, 2.2).And("myOtherField^0.3"), Query = "hello world", }
Example json output.
{ "multi_match": { "query": "hello world", "fields": [ "description^2.2", "myOtherField^0.3" ] } }
