如何在solr中比较日期？

我的模式有两个字段

<field name="startDate" type="date" indexed="true" stored="true"/>
<field name="endDate" type="date" indexed="true" stored="true"/>

我需要搜索“当前时间”介于开始日期和结束日期之间的文档

查询将是什么？

一个查询字符串，为了清楚起见没有转义，可能看起来像这样（使用lucene查询解析器语法）：

如果使用Solr“DateField”类型，那么对这些字段的任何查询（通常是范围查询）都应该使用字段支持的完整ISO 8601日期语法，或者使用DateMath语法来获取相对日期。示例：

timestamp:[* TO NOW]
createdate:[1976-03-06T23:59:59.999Z TO *]
createdate:[1995-12-31T23:59:59.999Z TO 2007-03-06T00:00:00Z]
pubdate:[NOW-1YEAR/DAY TO NOW/DAY+1DAY]
createdate:[1976-03-06T23:59:59.999Z TO 1976-03-06T23:59:59.999Z+1YEAR]
createdate:[1976-03-06T23:59:59.999Z/YEAR TO 1976-03-06T23:59:59.999Z]

timestamp:[* TO NOW]
createdate:[1976-03-06T23:59:59.999Z TO *]
createdate:[1995-12-31T23:59:59.999Z TO 2007-03-06T00:00:00Z]
pubdate:[NOW-1YEAR/DAY TO NOW/DAY+1DAY]
createdate:[1976-03-06T23:59:59.999Z TO 1976-03-06T23:59:59.999Z+1YEAR]
createdate:[1976-03-06T23:59:59.999Z/YEAR TO 1976-03-06T23:59:59.999Z]
