Description
The documentation for the caching behaviour of querysets is misleading. It implies that queryset results are always cached, but in actual fact the cache is only set if the entire queryset is evaluated - not when a section of the queryset is queried (such as a call to queryset[3]).
I will attach a patch documenting this behaviour shortly.

This looks good to me as well. I've wrapped the lines and made some minor edits.

This looks useful and the proposed patch looks pretty good (
git applycomplains about trailing whitespace on line 25 though).I'm marking this as accepted.
I would mark it as ready for checkin too, but I feel this should get reviewed by a native speaker (which I'm not).
Thanks for your contribution.
