Bug: Cant anchor a search RE to end

If you try to anchor a search RE to the end using the $ RE operator, the expression fails to work correctly.

Test case

This search:

  • %SEARCH{search="StatusReport$" scope="topic"}%

will not find all topics that end in "StatusReport" as it should (in fact it doesn't find any).

This roughly similar search works for finding topics that don't begin with "StatusReport":

  • %SEARCH{search=".+StatusReport" scope="topic"}%

But it obviously isn't the same thing and it won't work in my application.

Follow up

No fix, just restating the problem: The $ anchor doesn't seem to work in a regular expression search, either on the search page or in an inline search. Is this the intended behavior?

For the time being, I will try the .+ workaround which might serve my purposes (temporarily) on the AbiWord TWiki -- I'll do some experimenting.

UPDATE: Although .+ works, that didn't solve my problem on the AbiWord TWiki FAQ, but I did arrange things so that ^ does. Still, this is, AFAICT, a bug, and should be left open until it's either fixed or documented.

This should be moved to the support web, I added these comments here to try to call attention to this existing topic.

Fix record

This is fixed now. The problem was that a search with scope="topic" does search for files ending in *.txt, causing the the $ RE operator to fail.

>         if( $theScope eq "topic" ) {
>             # Fix for Codev.CantAnchorSearchREToEnd
>             @tokens = map { s/\$$/\\\.txt\$/o; $_ } @tokens;

In TWikiAlphaRelease and TWiki.org.
