使用 java api 的 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

我想将 3 个字段用于此搜索，即

department
job
name

我想搜索与 "department: D1"、"department: D2"、"job: J1"、"job: J2" "name: N1" 等字段匹配的 return 文档

我一直在尝试这样做

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，查询的执行就像每个查询都是一个单独的查询一样，即在这个例子中，当 j3 存在于 d4 中时，具有 d4 的文档也将被匹配

如何按照我说的方式进行搜索？我一直在尝试许多不同的查询，但似乎没有任何效果，我是否遗漏了什么？

Answer 1

您不想使用 MultiSearchRequestBuilder，您只需要在 bool/filter 查询中组合您的三个约束：

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"));
    SearchRequest searchRequest = new SearchRequest();
    searchRequest.indices("posts-1","posts-2").source(sourceBuilder);
    SearchResponse searchResponse = client.search(searchRequest);
    RestStatus status = searchResponse.status();
    System.out.println(searchResponse.toString());
