    var searchResponse = await client.SearchAsync<Product>(s => s
        .Index(_indexName)
        .Query(q => q

                .Query(q => q
                    .MultiMatch(mm => mm
                        .Query(query)

                        .Type(TextQueryType.BestFields)
                        .Fuzziness(new Fuzziness(1))
                        .MinimumShouldMatch("75%")
                    )
                )
                .BoostMode(FunctionBoostMode.Multiply)
