類比mysql，我們需要=、>、>=、<、<= 、or、and、in、like、count、sum、group by、order by、limit 

在高版本的ES裡面使用了boolquery替換了filter

1、等於號=

1. QueryBuilders.termQuery("isDel",1));

2. //termQuery相當於=，相當於isDel=1

2、大於小於號

1. QueryBuilders.rangeQuery("overdueStartTime").lte(startDate.getTime())

2. //rangeQuery

3. //lte <=

4. //lt <

5. //gte >=

6. //gt >

3、or、and

1. boolQueryBuilder.must(QueryBuilders.termQuery("isDel",req.getIs_del()));

2. //must相當於and

3. caseStatusQuery.should(QueryBuilders.termQuery("caseStatus",s));

4. //should相當於or

4、in

1. QueryBuilders.termsQuery("clientCompanyId",req.getClientCompanyIdList())

2. //termQuery相當於in，可以傳遞list

5、like

1. QueryBuilders.wildcardQuery("phone1", "*" + req.getTelephone() + "*")

2. //wildcard 正則匹配

3. QueryBuilders.matchPhraseQuery("debtorName", req.getDebtor_name())

4. //matchPhrase 不會分詞，直接匹配有完整相關短語的記錄

6、sum&&count

1. AggregationBuilder debtTotalSum = AggregationBuilders.sum(DEBT_TOTAL_SUM_KEY).field("debtTotal");

2. AggregationBuilder debtTotalCount = AggregationBuilders.count(DEBT_TOTAL_COUNT_KEY).field("debtTotal");

7、order by and limit

1. SearchResponse searchResponse = client.prepareSearch(ElasticSearchUtil.getIndexName())

2. .setTypes(ElasticSearchUtil.TYPE_NAME)

3. .setQuery(boolQueryBuilder)

4. //指定查詢欄位

5. .addStoredField("id")

6. .addSort(order, sortOrder)

7. //分頁

8. .setFrom((currentPage - 1) * limit).setSize(limit)

9. .execute()

10. .actionGet();

8、批量插入

1. public void batchInsert(List<CaseTable> list,Client client) {

2. LOGGER.info("---------案件批量插入索引開始--------");

3. BulkRequestBuilder bulkRequest = client.prepareBulk();

4. long start = System.currentTimeMillis();

5. BulkRequestBuilder delRequest = client.prepareBulk();

6. for (CaseTable caseTable :list){

7. IndexRequestBuilder ir = client.prepareIndex()

8. .setIndex(ElasticSearchUtil.INDEX_NAME_CASE)

9. .setType(ElasticSearchUtil.TYPE_NAME_CASE)

10. .setId(caseTable.getId().toString())

11. .setSource(JSON.toJSONString(caseTable));

12. bulkRequest.add(ir);

13. start = System.currentTimeMillis();

14. BulkResponse bulkResponse = bulkRequest.execute().actionGet();

15. LOGGER.info("案件批量插入迴圈所用時間 search time:{}ms", System.currentTimeMillis() - start);

16. if (!bulkResponse.hasFailures()) {

17. LOGGER.info("----------案件批量插入成功一輪------------");

18. }

19. }
