How using fl in query affects query time
Hi,
I am having around 100 fields in single document. I want to know that if I
use fl and get only single field from query will that reduce query time??
or getting all the fields through query and getting one field using fl in
query both will have same query time??

I believe enableLazyFieldLoading setting is supposed to help with the
partial-fields use-case. But not with query time itself, but with
re-hydrating stored fields to return. Which I guess is part of the
query time from the user's point of view.
