ElasticSearch（2.2）startDate和endDate之间的Java过滤器（如果存在）

您需要这样的查询：

BoolQueryBuilder startDateQuery = new BoolQueryBuilder()   .should(QueryBuilders.missingQuery("startDate"))   .should(QueryBuilders.rangeQuery("startDate").lte("now"))   .minimumShouldMatch(1);BoolQueryBuilder endDateQuery = new BoolQueryBuilder()   .should(QueryBuilders.missingQuery("endDate"))   .should(QueryBuilders.rangeQuery("endDate").gte("now"))   .minimumShouldMatch(1);BoolQueryBuilder queryBuilder = new BoolQueryBuilder()   .filter(startDateQuery)   .filter(endDateQuery);
