Description Ævar Arnfjörð Bjarmason 2006-01-21 02:21:04 UTC 
Querypage (and by extension classes that inherit it) shouldn't use LIMIT to do
paging as this gets exponentially more expensive the further into the set one
goes, it should use shomething like title >= x AND namespace => y like
Special:Contributions does. This would allow raising the number of rows inserted
into `querycache` for a given page without it bogging down the server(s).

1) A "nice to have" feature would be a "from=" parameter which should be
supported in wiki syntax [[special:foo/bar]].
2) See:
Bug 4927: User interface should substitute "_" consistently with space (%20) in
the from= parameter
3) trivial: The parameters should be supported in the user interface.

addition to comment #1
4) Support both "from=<pagename>" and "namespace=<namespace>" with wiki syntax
[[special:foo/<namespace>:<pagename>]]

I submitted a patch for Bug 2415 which accomplishes paging without the use of LIMIT.
