Question

The Ref-By link on every page returns no results. It displays My *Topic *Name &#42[&A-Za-z] at the top, but there are always 0 results.

If I enter the search phrase manually into WebSearch, it finds plenty of matches.

This is failing on a Solaris/Zeus setup. Everything worked fine when my TWiki setup was installed with a different web hosting provider.

• TWiki version: 20001201
• Web server: Zeus
• Server OS: Solaris

I'm having exactly the same problem on my Linux installation of the Dec2000 production release. I can go to the WelcomeGuest page (hardly what you'd call unreferenced), click the Ref-By link and come up empty.

More info please

Would that be: *My *Topic *Name *[A-Za-z]* ????, &42;My &42;Topic &42;Name &42;[A-Za-z]&42;, or is it as you wrote in your question?? (remember that different browsers display some tags differently, so I want to be sure).

Anyway, it sounds like a Perl version incompatibility.

Hmm. I've seen a similar problem on our server (NT4sp6, Perl 5.6.0 (Active Perl 623)). Haven't had time to determine why it happens.

I just got this on the July beta by clicking on "ref-by" on topic "DavidLeBlanc":

Actually, i'm completely astounded that it returned more then the last 2 lines, which is close to what it's always returned before.

Same issue on my end (2 Dec 2000). Ref-By returns zip!

However, I noticed that this works on twiki.org. I also noticed the search seems to be missing "scope=text"

Sooo ...

In the master view.tmpl file, I edited the href with "Ref-By" in it such that:

 ?web=all&

reads this way instead

 ?scope=text&web=all&

Then again, scope=text may be default behavior anyway (?).

Update - if you use spaces in your Wiki Names, that is, if you use [[Names Like This]], then it seems to work, but NamesLikeThis do not seem to work.

It's as if the zero-or-more spaces bit is being interpreted as one-or-more, or perhaps something else.

BTW, kudos to the folks responsible for using the more proper & instead of &. "Of course, the semicolon ; should really be the preferred separator."

Still no answer and I've got the same problem. Is this addressed in the upcoming release? We can't do categories the way we're used to on Meatball wiki.

Ref-by is critical! (Dec 2000 version on solaris, apache)

...after doing some research, it seams to have to do with an empty web list...will put findings here as I discover.

...found the problem. Have to go home so can't fix it right now, but in search script, line 73 I think (I've tweaked the file a little). Code is trying to split on ampersands and query string is separated with semicolons. If anyone is reading this and the fix is NOT to change what the split is on, please let me know. -- ChristianHall

Changed line 73 from

split('&', $query->query_string);

to

split(/[&;]/, $query->query_string);

which fixed the problem.

Note: we use Mod Perl...which may have some effect.
