how to set start when pagination.
I'm not sure I understand the question.
When combining results from partitions, you can't use startAt. You
must always assemble the docs from 0 to N for each partition (whether
through one request or multiple).

yes, partitions distrbuted.
Double or triple that (and put a minimum

i dont' know what u mean "runs out"
one user request will generate 60 partitions request.
they work in parallel。
so i don't know every partion's status before they done.
To promise 10 page result sorted by score correctly, the only way
seems to
get 100 results(rows=100) from each partitioin. but it very slow.
now i wanna find a way to get result sorted by score correctly and
search
fast.
