Is there really anyone who scans 250 items in a search result for the right one? In my experience (and custom search results tiddler) 30 results is more than enough for me to reach a point where I’d rather modify my query than go on scanning. But maybe I’m more impatient than others so take it with a grain of salt.
Anyway, just in case, I put in a message that informs about the limit being hit and contains a link to the config tiddler to change the limit as well as a button that launches the $:/AdvancedSearch with the corresponding query, which will show all the results, should I ever need that (never so far, though).
I believe that a usable and flexible search that lets one quickly find content is the most important feature for a (large) wiki. This is one of the reasons I love TW so much – you can just tailor the search (or nearly anything!) to your needs and are not stuck with what the system gives you, if you’re willing to put in the time. Regarding search, time put in < time saved.
Have a nice day

PS: Apart from different sort parameters, I implemented search within a selected tag hierarchy, selectively include journals, selectively highlight search results, result preview, selectively hide “All matches” for speed; all of which I find very useful. Since not all of that fits into a dropdown, I moved the search results into a sidebar tab, to make better use of that screen space. I’ve also seen other good ideas here on the forum.
