Elasticsearch Java API （三）：搜索

 Elasticsearch Java API （三）：搜索

 基本的条件查询是这样的

  QueryBuilder qb = termQuery("name",  "2");
        SearchResponse response = client.getClient().prepareSearch("gxk")
                .setQuery(qb).setSize(100).execute().actionGet();
        SearchHits hits = response.getHits();
        System.out.println("\n成功匹配到"+hits.getTotalHits()+"条结果！\n");
        if (hits.totalHits() > 0)
                for (SearchHit hit : hits)    System.out.println("搜索结果：/"+hit.getIndex()+"/"+hit.getType()+"/"+hit.getSourceAsString());

 

这里的client是（一）中定义的MyClient gxk是索引名称 setsize不用的话默认输出10条结果  name和2意思是查找name字段为2的
