Bug: Type=regex Search does not Work as Expected

I like to use searches rather than manual lists where I can, so I wanted TWikiGroups to search for access group definitions. I tried to create this search:

%SEARCH{"Group$" scope="topic" noheader="on" nosearch="on" nosummary="on" type="regex"}%

Test case

(in each of the stages below I have used "Expected" instead of "Group" as the end of the topic name I want, to demonstrate the results when the query is run in this web)

OK, searching for topics whose names end in "Expected".

%SEARCH{"Expected$" scope="topic" noheader="on" nosearch="on" nosummary="on" type="regex"}%

So, cribbing the documentation, I limited it to a range of topics:

%SEARCH{"Expected$" scope="topic" topic="*Expected" noheader="on" nosearch="on" nosummary="on" type="regex"}%

Nope, still no joy. So I searched for the empty string instead, since all the topics should contain it:

%SEARCH{"" scope="topic" topic="*Expected" noheader="on" nosearch="on" nosummary="on" type="regex"}%

Losing patience, I tried this instead:

%SEARCH{"Expected" scope="topic" topic="*Expected" noheader="on" nosearch="on" nosummary="on" type="regex"}%

BTW, using regex="on" instead of type="regex" does this:

%SEARCH{"Expected$" scope="topic" noheader="on" nosearch="on" nosummary="on" regex="on"}%

%SEARCH{"Expected$" scope="topic" topic="*Expected" noheader="on" nosearch="on" nosummary="on" regex="on"}%

%SEARCH{"" scope="topic" topic="*Expected" noheader="on" nosearch="on" nosummary="on" regex="on"}%

%SEARCH{"Expected" scope="topic" topic="*Expected" noheader="on" nosearch="on" nosummary="on" regex="on"}%

Follow up

This is a bug cloned from Support.SearchDoesNotWorkAsExpected. type="regex" and regex="on" (deprecated) should behave the same.

Fix record

Fix is in TWikiAlphaRelease (not yet at TWiki.org)
