Question

有多个文档，每个文档包含大约100个字段。我想通过elasticsearch Java API 5.x执行以下搜索：

我想在此搜索中使用3个字段，即

department
job
name

我希望搜索与＆＃34; department：D1＆＃34;，＆＃34; department：D2＆＃34;，＆＃34; job：J1＆＃34; ，＆＃34;工作：J2＆＃34; ＆＃34;名称：N1＆＃34;

我一直试图这样做

String[] departments = ["d1","d2","d3"];
String[] jobs = ["j1","j2","j3"];
String[] names = ["n1"];

MultiSearchRequestBuilder requestbuilder; 

requestBuilder.add(client.prepareSearch().setQuery(QueryBuilders.termsQuery("department", departments)));
requestBuilder.add(client.prepareSearch().setQuery(QueryBuilders.termsQuery("job", jobs)));
requestBuilder.add(client.prepareSearch().setQuery(QueryBuilders.termsQuery("name", names)));

MultiSearchResponse response = requestBuilder.get();

然而，执行查询就好像每个查询都是一个单独的查询，即在这个例子中，当d4中存在j3时，带有d4的文档将被匹配以及

如何以我提到的方式进行搜索？我一直在尝试各种不同的查询，似乎没有任何工作，我有什么遗漏吗？

Answer 1

您不想使用MultiSearchRequestBuilder，只需在bool/filter查询中合并三个约束：

BoolQueryBuilder query = QueryBuilders.boolQuery()
   .filter(QueryBuilders.termsQuery("department", departments))
   .filter(QueryBuilders.termsQuery("job", jobs))
   .filter(QueryBuilders.termsQuery("name", names));
SearchResponse resp = client.prepareSearch().setQuery(query).get();

对于使用HighRestClient的Elasticsearch 5.6.4，添加所需数量的sourcebuilder ...

static RestHighLevelClient client = new RestHighLevelClient(RestClient.builder(new HttpHost("localhost", 9200, "http")));
public static void multisearch() throws IOException{
    SearchSourceBuilder sourceBuilder = new SearchSourceBuilder(); 
    sourceBuilder.query(QueryBuilders.termQuery("name", "vijay1"));
    SearchSourceBuilder sourceBuilder1 = new SearchSourceBuilder(); 
    sourceBuilder.query(QueryBuilders.termQuery("name", "vijay"));
    SearchRequest searchRequest = new SearchRequest();
    searchRequest.indices("posts-1","posts-2").source(sourceBuilder).source(sourceBuilder1);
    SearchResponse searchResponse = client.search(searchRequest);
    RestStatus status = searchResponse.status();
    System.out.println(searchResponse.toString());

使用java api进行Elasticsearch多条件查询
