SCREENSHOT我已经创建了一个自定义元数据字段（日期类型），现在我想在DSpace中搜索包含元数据字段的对象，并且匹配日期范围是可能的吗？我想我需要一个自定义元数据的搜索过滤器。所以我将此字段配置为Discovery（SOLR）搜索过滤器
是否足以将元数据字段添加到config / spring / api / discovery.xml中的下面列表中
>> >> <property name="searchFilters">
>> >> <list>
>> >> <ref bean="searchFilterTitle" />
>> >> <ref bean="searchFilterAuthor" />
>> >> <ref bean="searchFilterSubject" />
>> >> <ref bean="searchFilterIssued" />
>> >> </list>
>> >> </property>
并在文件底部配置它，配置其他过滤器
https://github.com/DSpace/DSpace/blob/master/dspace/config/spring/api/discovery.xml#L363
现在我已经完成了所有这些，但搜索不起作用。我在源代码中完成了mvn包，并在cd dspace / target / dspace4-0build ant update中完成了./dspace index-discovery
我仍然无法让这个工作，请你有什么建议吗？
以下是我的discovery.xml的内容
<?xml version="1.0" encoding="UTF-8"?>

听起来你走在正确的轨道上。
如果有用，下面的示例文件会说明我们配置的几个自定义构面：https://gist.github.com/terrywbrady/d31fc1bcb9567204470f
