Actually I have to rewrite my question:
Query 1:
q=*:*&rows=row_count&sort=id asc&start=X
and
Query2:
q={X TO *}&rows=row_count&sort=id asc&start=0

> The second query excludes documents matched by [* TO X], while the first
> query matches all documents.
>
> Relative performance will depend on relative match count and the sort time
> on the matched documents. Sorting will likely be the dominant factor - for
> equal number of documents. So, it depends on whether starting with X
> excludes or includes the majority of documents, relative to whatever
> row_count might be.
>
> Generally, you should only sort a small number of documents/results.

> Or, consider DocValues since they are designed for sorting.
