在DSpace中搜索包含自定義元數據字段並匹配日期範圍的對象

Question

SCREENSHOT我製作了自定義元數據字段（日期類型），現在我想搜索DSpace中的對象，該對象包含元數據字段，並匹配日期範圍是可能的？我想我需要一個搜索過濾器來定製我的元數據。所以我配置了該領域的發現（SOLR）搜索過濾器

它應該是足夠的元數據字段添加到列表下方的config /春/ API/discovery.xml

>> >>   <property name="searchFilters"> 
>> >>    <list> 
>> >>     <ref bean="searchFilterTitle" /> 
>> >>     <ref bean="searchFilterAuthor" /> 
>> >>     <ref bean="searchFilterSubject" /> 
>> >>     <ref bean="searchFilterIssued" /> 
>> >>    </list> 
>> >>   </property> 

，也在該文件的底部，這裏的其他過濾器配置

https://github.com/DSpace/DSpace/blob/master/dspace/config/spring/api/discovery.xml#L363

現在我所做的這一切，但搜索行不通配置。我已經完成源和光盤dspace /目標/ dspace4-0build螞蟻更新然後./dspace索引發現mvn包

我仍然無法得到這個工作，請你有任何意見？

這裏是我的discovery.xml的內容

Answer 1

這聽起來像你在正確的軌道上。

1. 定義新過濾器併爲其分配一個唯一的ID。
2. 將新過濾器添加爲搜索過濾器和側欄。
3. 如果您的新過濾器適用於日期字段，請確保您的日期採用YYYY-MM-DD格式。
4. 更改部署，重新啓動DSpace的
5. 重建索引庫，迫使項目進行重新索引
