Alexander S. created SOLR-6494:
----------------------------------
Summary: Query filters applied in a wrong order
Key: SOLR-6494
URL: https://issues.apache.org/jira/browse/SOLR-6494
Project: Solr
Issue Type: Bug
Affects Versions: 4.8.1
Reporter: Alexander S.
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.
