【ElasticSearch実戦】——ES常用照会条件とmysql比較

クラス比mysqlは、=、>、>=、and、in、like、count、sum、group by、order by、limitが必要です.
高バージョンのESではboolqueryを使用してfilterを置き換えました
1、等号=

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

2、より小さい

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

3、or、and

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

4、in

QueryBuilders.termsQuery("clientCompanyId",req.getClientCompanyIdList())
//termQuery   in，    list

5、like

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

QueryBuilders.matchPhraseQuery("debtorName", req.getDebtor_name())
//matchPhrase     ，

6、sum&&count

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

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

7、order by and limit

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

8、一括挿入

public  void batchInsert(List list,Client client) {
        LOGGER.info("---------          --------");
        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("             search time:{}ms", System.currentTimeMillis() - start);
        if (!bulkResponse.hasFailures()) {
            LOGGER.info("----------          ------------");
        }
    }
