First scroll search,I got the response,then I calculate the datas using 10 seconds.And then I do the secound scroll search,,,,,,  
Hypothesis:Every time,using 10 seconds to calculate the datas.

So,"Keeping the search context alive" must gr 10 seconds?

Yes. You must return before the deadline you set for yourself expires. If you said you’d be back in 10 seconds but took 12 then that ship has already sailed.
