Does this site look broken?. Use the LitterTray web for test cases.
same as cairo, so i'm marking this as an enhancement


Probably good to introduce a new parameter toplimit (or the like) to limit the total number of hits. This is for compatibility.

This would be a real treat. Have had a suggestions from users to use some top space (WebTopBar) for a "last 5 changed topics, globally"-style info area, but this is not easy to implement using current search.

I hope you are right, CC smile

Looking at the code, naively I'd probably jump in around line 949 in Search.pm, where all webs has been searched. - Unfortunately, everything is rendered more or less up at this point, so I guess the only simple opportunity left (without a major refactor) is simply regexp'ing the $searchresult for $separator, taking first $toplimit matches and cutting the rest.

In cases where the search result contains $separators on it's own, this will of course not work reliably, but I'm having problems imagining any real life searches where this would actually be a problem.

Other solutions, or will this work? I.e. something like:

Whooops, completely missed the fact that topics are not globally sorted in $searchResult, but only sorted "per web". This means giving up on the easy part for me.

-- SP

This topic was lost from the lists due to not having a codebase field. Rediscovered 3/2/07.


No spec change please. New paramter is ok.

-- PTh

I would find limitall a more intuitive name, alongside limitweb, while limit is maintained for compatibility.

-- TWiki:Main.ArthurClemens - 03 Feb 2007

Sounds like it's just waiting for an implementor. Set status accordingly.


new limitall and limitweb, keeping limit as undocumented feature sounds like a plan.

-- TWiki:Main.PeterThoeny - 05 Feb 2007

Summary SEARCH limit parameter applies to each web/subweb, not total number of matches
