【ElasticSearch实战】——ES常用查询条件与mysql对比

类比mysql，我们需要=、>、>=、<、<= 、or、and、in、like、count、sum、group by、order by、limit 

在高版本的ES里面使用了boolquery替换了filter

1、等于号=

("isDel",1));
//termQuery相当于=，相当于isDel=1

• 1
• 2

2、大于小于号

QueryBuilders.rangeQuery("overdueStartTime").lte(startDate.getTime())
//rangeQuery 
//lte   <=
//lt    <
//gte   >=
//gt    >

• 1
• 2
• 3
• 4
• 5
• 6

3、or、and

boolQueryBuilder.must(QueryBuilders.termQuery("isDel",req.getIs_del()));
//must相当于and
caseStatusQuery.should(QueryBuilders.termQuery("caseStatus",s));
//should相当于or

• 1
• 2
• 3
• 4

4、in

QueryBuilders.termsQuery("clientCompanyId",req.getClientCompanyIdList())
//termQuery相当于in，可以传递list

• 1
• 2

5、like

QueryBuilders.wildcardQuery("phone1", "*" + req.getTelephone() + "*")
//wildcard 正则匹配

QueryBuilders.matchPhraseQuery("debtorName", req.getDebtor_name())
//matchPhrase 不会分词，直接匹配有完整相关短语的记录

• 1
• 2
• 3
• 4
• 5

6、sum&&count

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

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

• 1
• 2
• 3

7、order by and limit

SearchResponse searchResponse = client.prepareSearch(ElasticSearchUtil.getIndexName())
                .setTypes(ElasticSearchUtil.TYPE_NAME)
                .setQuery(boolQueryBuilder)
                        //指定查询字段
                .addStoredField("id")
                .addSort(order, sortOrder)
                        //分页
                .setFrom((currentPage - 1) * limit).setSize(limit)
                .execute()
                .actionGet();

• 1
• 2
• 3
• 4
• 5
• 6
• 7
• 8
• 9
• 10

8、批量插入

public  void batchInsert(List<CaseTable> list,Client client) {
        LOGGER.info("---------案件批量插入索引开始--------");
        BulkRequestBuilder bulkRequest = client.prepareBulk();
        long start = System.currentTimeMillis();
        BulkRequestBuilder delRequest = client.prepareBulk();

        for (CaseTable caseTable :list){
            IndexRequestBuilder ir = client.prepareIndex()
                    .setIndex(ElasticSearchUtil.INDEX_NAME_CASE)
                    .setType(ElasticSearchUtil.TYPE_NAME_CASE)
                    .setId(caseTable.getId().toString())
                    .setSource(JSON.toJSONString(caseTable));
            bulkRequest.add(ir);

        start = System.currentTimeMillis();
        BulkResponse bulkResponse = bulkRequest.execute().actionGet();
        LOGGER.info("案件批量插入循环所用时间 search time:{}ms", System.currentTimeMillis() - start);
        if (!bulkResponse.hasFailures()) {
            LOGGER.info("----------案件批量插入成功一轮------------");
        }
    }
