如何使用ElasticSearch DSL C#降低与特定字段和值匹配的文档的分数

using Nest;

var settings = new ConnectionSettings(new Uri("http://localhost:9200"));
var client = new ElasticClient(settings);

var searchRequest = new SearchRequest<YourDocumentType>
{
    Query = new BoolQuery
    {
        Must = new List<QueryContainer>
        {
            new MatchQuery
            {
                Field = "your_field_name",
                Query = "your_field_value"
            }
        },
        Should = new List<QueryContainer>
        {
            new MatchQuery
            {
                Field = "your_specific_field_name",
                Query = "your_specific_field_value",
                Boost = 0.5 // 设置特定字段的权重，降低匹配文档的分数
            }
        }
    }
};

var searchResponse = client.Search<YourDocumentType>(searchRequest);
