java 调用es使用query语法对一个字段进行模糊匹配多个值比如名字里带 a或者c或者d的具体查询语句怎么写dsl的json字符串怎么拼接

您可以使用Bool Query结合Wildcard Query实现对一个字段进行模糊匹配多个值的查询。

以下是一个示例的Java代码，展示了如何使用Java High Level REST Client调用Elasticsearch进行模糊匹配查询：

import org.elasticsearch.action.search.SearchRequest;
import org.elasticsearch.action.search.SearchResponse;
import org.elasticsearch.client.RequestOptions;
import org.elasticsearch.client.RestClient;
import org.elasticsearch.client.RestHighLevelClient;
import org.elasticsearch.index.query.BoolQueryBuilder;
import org.elasticsearch.index.query.QueryBuilders;
import org.elasticsearch.index.query.WildcardQueryBuilder;
import org.elasticsearch.search.builder.SearchSourceBuilder;

import java.io.IOException;

public class ElasticsearchQueryExample {
    public static void main(String[] args) {
        String[] values = {"a", "c", "d"};

        try (RestHighLevelClient client = new RestHighLevelClient(
                RestClient.builder("localhost:9200"))) {

            BoolQueryBuilder boolQuery = QueryBuilders.boolQuery();
            for (String value : values) {
                WildcardQueryBuilder wildcardQuery = QueryBuilders.wildcardQuery("name", "*" + value + "*");
                boolQuery.should(wildcardQuery);
            }

            SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();
            sourceBuilder.query(boolQuery);

            SearchRequest searchRequest = new SearchRequest("your_index");
            searchRequest.source(sourceBuilder);

            SearchResponse searchResponse = client.search(searchRequest, RequestOptions.DEFAULT);
            // 处理搜索结果
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

上述代码中，我们使用Bool Query的should子句来实现对多个Wildcard Query的逻辑OR操作，将查询"名字里带a或者c或者d"的文档。
