elastic查询笔记（2）

这几天又遇到个问题，elastic的数据结构差的不多如下：

"labelInfo":  [        {        "id":1/*产品推荐ID*/               "labelId":1,         "departDate":"2015-11-28",         "labelName":"主推",         "labelNotes":"标签备注",         "updateUserName":"谁",         "updateTime":"2015-11-0611: 05: 00"       },       {         "id":2/*产品推荐ID*/             "labelId":-1,         "departDate":"2015-11-30",         "labelName":"主推",         "labelNotes":"标签备注",         "updateUserName":"谁",         "updateTime":"2015-11-0611: 05: 00"       }      ]

是一个list的结构，业务需求是查询labelId为1同时日期在2015-11-29之后的，一直不知道怎么组装querybuilder才能满足这条件，直到今天百度上搜搜看到有个国外老司机在NestedQueryBuilder里又放了个BoolQueryBuilder 陡然茅塞顿开啊。。（链接手残关掉了，历史记录都没找到。。）部分代码如下：

 if (request.get("proLabelList") != null && !labelList.isEmpty()) {            BoolQueryBuilder bQueryBuilder = new BoolQueryBuilder();            bQueryBuilder.must(new TermsQueryBuilder("labelInfo.labelId", labelList));            if (!StringUtil.isEmptyString(startDate) && !StringUtil.isEmptyString(endDate)) {                bQueryBuilder.must(new RangeQueryBuilder("labelInfo.departDate").gte(startDate).lte(endDate));            } else if (!StringUtil.isEmptyString(startDate) && StringUtil.isEmptyString(endDate)) {                bQueryBuilder.must(new RangeQueryBuilder("labelInfo.departDate").from(startDate));            } else if (StringUtil.isEmptyString(startDate) && !StringUtil.isEmptyString(endDate)) {                bQueryBuilder.must(new RangeQueryBuilder("labelInfo.departDate").to(endDate));            }            boolQueryBuilder.must(new NestedQueryBuilder("labelInfo", bQueryBuilder));        }
