Erick Erickson resolved SOLR-6494.
----------------------------------
    Resolution: Invalid

First, please raise issues like this on the user's list first to insure that 
it's really a bug before raising JIRAs.

Second, I don't think you understand how filter queries work. By design, fq 
clauses like this are calculated for the entire document set and the results 
cached, there is no "ordering" for that part. Otherwise, how could they be 
re-used for a different query?

You can get around this by specifying "non-cached" filters, or just pay the 
price the first time and be able to re-use the cache later, perhaps with 
warming queries creating the filter (assuming it's a common one) to hide the 
pain of first-time use.

> This query:
> {code}
> {
>   fq: ["type:Award::Nomination"],
>   sort: "score desc",
>   start: 0,
>   rows: 20,
>   q: "*:*"
> }
> {code}
> takes just a few milliseconds, but this one:
> {code}
> {
>   fq: [
>     "type:Award::Nomination",
>     "created_at_d:[* TO 2014-09-08T23:59:59Z]"
>   ],
>   sort: "score desc",
>   start: 0,
>   rows: 20,
>   q: "*:*"
> }
> {code}
> takes almost 15 seconds.
> I have just ≈12k of documents with type "Award::Nomination", but around half 
> a billion with created_at_d field set. And it seems Solr applies the 
> created_at_d filter first going through all documents where this field is 
> set, which is not very smart.
> I think if it can't do anything better than applying filters in the alphabet 
> order it should apply them in the order they were received.
