LUCENE-10119: Do not set single sort with search after (#317)
We should not set single sort when the search_after is non-null;
otherwise, we will incorrectly skip documents whose values are equal to
the value from the search_after and docIDs are greater than the docID
from the search_after.

> Key: LUCENE-10119
> URL: https://issues.apache.org/jira/browse/LUCENE-10119
> Project: Lucene - Core
> Issue Type: Bug
> Components: core/search
> Affects Versions: main (9.0), 8.10
> Reporter: Nhat Nguyen
> Assignee: Nhat Nguyen
> Priority: Major
> Time Spent: 50m
> Remaining Estimate: 0h
>
> Today we set the parameter `singleSort` to true when we have a single
> comparator to skip documents whose values equal the last visited value.
> However, this is incorrect when the search_after parameter is non-null as
> that we will skip documents whose values are equal, but their docIDs are
> greater than the docID of the `search_after` parameter.
>
> We found this issue in Elasticsearch after upgrading it to Lucene 8.10 and
> Lucene 9.
