match查询

  1. @Test
  2. public void testMatchSearch(RestHighLevelClient client) throws IOException {
  3.     // 基础设置   new SearchRequest("patent"); "patent" 为索引名称
  4.     SearchRequest searchRequest = new SearchRequest("patent");
  5.     // 搜索源构建对象
  6.     SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
  7.     // 匹配关键字
  9.     searchSourceBuilder.query(
  10.         QueryBuilders.matchQuery("relation_ship", "one integrated can not replace")
  11.         .minimumShouldMatch("1%"));   //minimumShouldMatch 最小匹配度
  12.     searchRequest.source(searchSourceBuilder);
  13.     // 发起请求，获取结果
  14.     SearchResponse searchResponse = client.search(searchRequest, RequestOptions.DEFAULT);    //注意默认返回10条数据  解决办法可以用分页查询，具体实现 下面第一快代码有
  15.     SearchHits hits1 = searchResponse.getHits();
  16.     SearchHit[] searchHits1 = hits1.getHits();
  17. }

prefixQuery前缀搜索

  1. {
  2.     "query": {
  3.         "prefix": {
  4.             "area": "华中"
  5.         }
  6.     }
  7. }

java代码

  1.     // 查找包含带有指定前缀term的文档
  2.     public static void basePrefixQuery() throws IOException {
  3.         SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();
  4.         sourceBuilder.query(QueryBuilders.prefixQuery("area","华中"));
  6.         SearchRequest request = new SearchRequest(INDEX);
  7.         request.source(sourceBuilder);
  8.         SearchResponse search =
  9.             getClient().search(request, RequestOptions.DEFAULT);
  11.         if (search.getShardFailures().length == 0) {
  12.             System.out.println("do something");
  13.         }
  14.     }
