使用java api进行Elasticsearch多条件查询

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:

有3个字段我想用于此搜索,即

department
job
name

我想搜索匹配"department:D1","department:D2","job:J1","job:J2""name:N1"等字段的返回文档

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();

但是,执行查询就好像每个查询都是单个查询一样,即在本例中当d4中存在j3时,带有d4的文档将被匹配

如何按照我提到的方式进行搜索？我一直在尝试各种不同的查询,似乎什么都没有用,有什么我想念的吗？

您不想使用MultiSearchRequestBuilder,只需在bool/filter查询中组合三个约束:

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();
