If a query type search is done

i.e. %SEARCH{"Category='Test'" type="query"}%

it work fine until over 150 topics are present in your web. Once 150 topics are reached, the search does not return anything.

I could not reproduce this - Glenn, prehaps you can tell us more about your setup?

-- SvenDowideit - 17 Jul 2008

I am running TWiki on Windows XP machine with Active Perl 5.8.8 Build 820 and Apache 2.2 (the Twiki 4.2 download from twiki.org). I don't believe I made any radical configuration changes. Is there anything specific you are looking for?

-- TWiki:Main.GlennHart - 18 Jul 2008

Glenn - thanks - it wouldn't surprise me if XP was the specific.

TWiki:Codev.GeorgetownReleaseMeeting2008x07x21 decided to downgrade to normal since noone can reproduce this.

-- TWiki:Main.KennethLavrsen - 22 Jul 2008

I think i've reproduced it (on windows), and will try to fix it for 4.2.1.. marked as urgent until its either fixed, or the release day comes.

-- SvenDowideit - 30 Jul 2008

looks like grep on windows is falling over - changing to use PurePerl fixes it - though is probably slower..

-- TWiki:Main.SvenDowideit - 30 Jul 2008

ok, so I've found 2 bugs

  1. Forking Search algo builds the command line using 512 files - way more than windows copes with. (this issue)
  2. the command line for MyItems breaks - there are embedded and unescaped [^ ] chars in that topic that are ok on unix, and busted on Windows. see Item5849

-- TWiki:Main.SvenDowideit - 30 Jul 2008

found Item5854 while testing this

-- SvenDowideit - 31 Jul 2008

Cleaned "WaitingFor" field.
