Return the ranks of selected documents

[Joel Nothman <jn...@student.usyd.edu.au>]

I would like to evaluate the recall of a selection of documents in Solr  
(at different ranks/limits), given varying queries.

Ideally this means that for a given query, I would like Solr just to  
return the ranks of selected unique keys within the results.

Is there a way to do this apart from iterating through the results on the  
client-side?

So far I have only been told it is an unusual question on StackOverflow:  
http://stackoverflow.com/questions/7924146

Thanks,

If i understand you correctly, given a query MY_QUERY and a set of IDs 
(ID1, ID2, ID3, etc...) you would like to know the score of those IDs 
against that query?

that's fairly straight forward...

	?q=MY_QUERY&fq=id:(ID1 ID2 ID3 ...)
