Here is a link to the original support topic where this issue was first raised:


Here is the actual web address (on my intranet)


And here is the first line:

META:TOPICINFO{author="CarlosMelendez" date="1207274179" format="1.1" reprev="1.17" version="1.17"}

Note that I was able to fix issue this by setting the RCS SearchAlgorithm to the 'PurePerl' implementation instead of the default 'Forking" algorithm.

(The important fact is that this is on Windows..)

ok, I did some investigation into this - and I have solved some of the issues, but at least one cannot be solved.

Basically, Windows has a very braindead approach to quotes, square brackets and pipe symbols - if you make a twiki SEARCH that contains an odd number of " characters, I have not found a reliable way to escape them so that execing grep does not fail.

I've fixed (for 4.2.1) several other cases, including the use of [^] - but PurePerl or NativeSearchContrib are more reliable.
