利用java api实现Elasticsearch多条件查询

Question

有多个文档，每个文档包含大约100个字段。我想执行以下搜索槽elasticsearch Java API5.x:

有3个字段我想用于这个搜索，即。

department
job
name

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();

Answer 1

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

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();
