Solr：通过查询部分更新删除值(Solr: remove value with partial update by query)

 我想从大索引中的多值字段中删除一个特定值，我需要先查询哪些文档包含该值，即： 
 
 
 
 检索包含特定值的文档的ID。 
 
 
 部分更新这些文件（使用remove ）。 
 
 
 Solr版本是5.1。 如有必要，我可以更新，但更改日志并不表示与此问题有任何关联。 
 
 我通过Solr Web界面（ http：// localhost：8983 / solr /＃/ core / documents ）在/select端点上尝试了以下查询（在一些变体中），尝试从所有文档中删除值： 
 
{"id":"*", "field": {"remove":"value"} }
 
 服务器响应“成功”，但没有更新文档。 
 
 我可以做的是查询field:value ，提取文档ID，并（以编程方式）为这些ID生成更新查询，类似于本答案中指出的内容。 但我希望应该有一个更直接的解决方案。 
 
 部分更新文档和其他相关网页中提供的示例在此处并不真正适用，因为它们假定已事先知道更新文档的ID。 关于类似问题的大多数其他讨论在引入部分更新之前（在Solr 4中）引用旧的Solr版本。 

I want to remove one specific value from a multivalued field in a large index, where I need to query first which documents contain that value, i.e.:
 
 
 
retrieve IDs of the documents containing the specific value.
 
 
partially update these documents (using remove).
 
 
Solr version is 5.1. I could update if necessary, but the change logs do not indicate any relevance to this issue.
 
I've tried the following query (in a few variations) on the /select endpoint through the Solr web interface (http://localhost:8983/solr/#/core/documents), trying to remove the value from all the documents:
 
{"id":"*", "field": {"remove":"value"} }
 
The server response is "success", but no document is updated.
 
What I could do is to query for field:value, extract the document IDs, and (programmatically) generate update queries for these IDs, similar to what has been indicated in this answer. But I would expect that there should be a more straight-forward solution. 
 
The examples presented in the partial updates documentation and other related web pages are not really applicable here because they assume that the ID of the updated documents are known in advance. Most other discussions about similar issues refer to old Solr versions, before partial updates were introduced (in Solr 4).
