Solr/Lucene是否有办法返回所选文档的排名而不是完整结果? [英] Is there a way for Solr/Lucene to return the ranks of selected documents instead of full results?
问题描述
我有兴趣通过查询 q 查询Solr并绘制出{10，20，30，...}文档为{em> D 的一组文档的调用图.返回.
I am interested in querying Solr with query q and charting its recall of a set of documents D when {10, 20, 30, ...} documents are returned.
目前，我得到了完整的结果，即(通过solrpy)返回的docid列表，并对其进行迭代以找到 D 的等级，即从 D 到搜索结果中的索引.我不严格要求映射，只要求映射等级.
Currently, I am having the full results, i.e. a list of docids returned (through solrpy), and iterate through it to find the ranks of D, i.e. a mapping from D to their indices in the search results. I do not strictly require the mapping, only mapped ranks.
是否有办法让一组ID的Solr/Lucene返回排名而不是完整结果?
Is there a way to have Solr/Lucene return ranks for a set of IDs instead of the full results?
其他解决此问题的方法:
Other ways of approaching this problem:
- 对于查询，返回文档 d 的等级
- 对于不超过指定等级的查询，返回是否存在文档 d
- 从查询 q1 的结果直到指定的记录数，返回与另一个查询 q2 匹配的记录数
- For a query, return the rank of document d
- For a query up to a specified rank, return whether or not document d is present
- From a query q1 result up to a specified number of records, return the number of records matched by another query q2
推荐答案
否，我想不出采用SOLR或Lucene的方式. 我认为这里最简单的解决方案是使用一个简单的HashSet对此进行编程...
No I cannot think of a SOLR or Lucene way to do this. I think the simplest solution here is to program this yourself with a simple HashSet...
