ES 中的and 和 or 查詢

 //跨索引查詢

SearchRequest request = new SearchRequest(index1,index2);

 在es中想實現類似於下面的查詢，廢話不多說，es的should查詢代替的是or，但是必須搭配must來使用

select * from table where (a != 1 and b != 1) or (startTime> “2022-05-20” and (a == 1 or b == 1)) 

 直接上代碼

 1 @Autowired
 2     private RestHighLevelClient client;
 3  public List<Map<String,Object>> searchList(String index1,String index2,Map<String,Object> paramMap
 4             ,String time,int page,int size) {
 5         List<Map<String,Object>> hitList = new ArrayList();
 6         try {
 7             //搜索請求
 8             SearchRequest request = new SearchRequest(index1,index2);
 9             //請求條件構建器,這裏和mybatis中的自定義查詢有點類型
10             SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();
11             BoolQueryBuilder boolQueryBuilder = QueryBuilders.boolQuery();
12 
13             //等於條件(其他的一些條件)
14             if (paramMap != null && !paramMap.isEmpty()) {
15                 paramMap.forEach((k, v) -> {
16                     boolQueryBuilder.must(QueryBuilders.termsQuery(k + KEYWORD, v));
17                 });
18             }
19 
20             
21                 BoolQueryBuilder query1 = QueryBuilders.boolQuery();
22                 query1.mustNot(QueryBuilders.termsQuery("a" + ".keyword", "1"));
23                 query1.mustNot(QueryBuilders.termsQuery("b" + ".keyword", "1"));
24 
25                 BoolQueryBuilder query2 = QueryBuilders.boolQuery();
26                 //時間範圍查詢
27                 if (StringUtils.isNotBlank(time)) {
28                     query2.must(QueryBuilders.rangeQuery("startTime"+KEYWORD).from(time));
29                 }
30 
31                 BoolQueryBuilder shouldQuery = QueryBuilders.boolQuery();
32                 shouldQuery.should(QueryBuilders.wildcardQuery("a" , "1"));
33                 shouldQuery.should(QueryBuilders.wildcardQuery("b" , "1"));
34                 query2.must(shouldQuery);
35 
36                 BoolQueryBuilder query3 = QueryBuilders.boolQuery();
37                 query3.should(query1);
38                 query3.should(query2);
39                 boolQueryBuilder.must(query3);
40            
41 
42             //把查詢添加放入請求中
43             sourceBuilder.query(boolQueryBuilder);
44             request.source(sourceBuilder);
45             //起始位置
46             sourceBuilder.from((page - 1) * size);
47             //查詢數量
48             sourceBuilder.size(size);
49             sourceBuilder.trackTotalHits(true);
50             //建立SearchResponse
51             SearchResponse response;
52          
53             response = client.search(request, RequestOptions.DEFAULT);
54             //封裝查詢的信息
55             for (SearchHit hit : response.getHits().getHits()) {
56                 hitList.add(hit.getSourceAsMap());
57                 log.debug("查詢結果:{}", hit.getSourceAsString());
58             }
59         } catch (IOException e) {
60             e.printStackTrace();
61         }
62         return hitList;
63     }

將每一塊拆成一個BoolQueryBuilder ，最後or用should()拼接起來
