[bounced here from https://bugzilla.mozilla.org/show_bug.cgi?id=308053]
If I search for some word, above the results (and below) are text/links to view
the previous 20, the next 20, and for setting the per-page results to
20/50/100/250/500. That's useful for big searches, but for small searches it's
just clutter. Basically, when all the available results are shown these links
For example, a search for "foobar" on the http://developer.mozilla.org/ wiki
currently returns 3 results. There's no reason to include the "previous 20" text
(on the first page?!), or the "next 20" link (there's only 3 total!).
I also don't really see any point in offering a results-per-page value greater
than the number of results. If the search returns 30 results, only the "20" and
"50" options would be useful. In fact, just labeling the maximum value as "All"
would seem a bit clearer. [unless this is sticky, in which case it would need to
be a specific number]
