The manual and most sites describe that startkey_docid can be used for quick pagination. Since I have only one parameter in the key, other methods are not appropriate.
I tried to use such requests but all in vain:

startkey_docid=s_7d60ea0ca71144339c54de10fab32eaa
startkey_docid="s_7d60ea0ca71144339c54de10fab32eaa"
startkey="l_u_adminadmincom_obzvon"&startkey_docid=s_7d60ea0ca71144339c54de10fab32eaa
startkey="l_u_adminadmincom_obzvon"&startkey_docid="s_7d60ea0ca71144339c54de10fab32eaa"
startkey="l_u_adminadmincom_obzvon"&endkey="l_u_adminadmincom_obzvonZ"&startkey_docid=s_7d60ea0ca71144339c54de10fab32eaa
startkey="l_u_adminadmincom_obzvon"&endkey="l_u_adminadmincom_obzvonZ"&startkey_docid="s_7d60ea0ca71144339c54de10fab32eaa"

Maybe someone came across and knows why it does not work. There are many such requests on the Internet and no one gives a complete answer on how to use it correctly.
For example, a few resources:
First
Second

Thanks in advance.

Answer 1

There is also an option to do pagination using skip, but then the question arises: if we make a request that reaches limit=1000 records by the limit and let’s write skip=2000, then we get 3000 records from the database and skip the first 2000 thousand or immediately skip 2000 and we get 1000. And how much slower will such a request work, in contrast to using startkey_docid?
SOLVED: In such cases, a query like

limit=10&key=%22l_u_adminadmincom_spisok-2014-07-23%22&startkey_docid=s_0cb04ab972de49e783c2cee7dfc688a6
