Item11190: SEARCH does not handle %WEB, %TOPIC etc. variables in the right context in the output

When a SEARCH finds variables like %WEB%, %TOPIC%, %ATTACHURL% etc. in the results, they get interpreted in the wrong context: Not in the topic they were found but in the topic where the SEARCH is.

This is a different interpretation of the variables compared to TWiki (up to 4.1.2).

Demo:

• TestTopic44738 contains and displays an image.
• TestTopic44739 contains a search which should show the image from above, but the generated URL for the picture is wrong.

Sorry, after checking the code, it turns out there is a "new" (?) parameter to SEARCH called expandvariables. If you set it (as I did in your examples, in a copy), you will see that it's working as expected.

I'm afraid the migration will have to edit the SEARCHes and add this parameter, as we cannot default to 1. In fact, we could have, when this was introduced, but I guess we decided against it for performance reason. Funny nobody complained before.

See: http://twiki.org/cgi-bin/view/Codev/ExpandVariablesOnFormattedSearch

I guess we can improve documentation - probably as an FAQ item.

Agreed. Leaving this task open to ensure what we have now is really what we want, and to improve the documentation accordingly.

No but wait... this parameter existed already, therefore my conclusions are wrong. The behavior changed, so are we happy with the way things are, or shall we change it?

-- OlivierRaginel - 20 Oct 2011

Which behaviour changed? The default for expandvariables?

-- PaulHarvey - 21 Oct 2011

Yes, the parameter already existed in TWiki 4.1.2 But it didn't expand all variables: %WEB% and %TOPIC% where not expanded.

So the actual foswiki behaviour is more logical but breaks with history.

I reccommend to leave it as it is now.

-- BeatDoebeli - 21 Oct 2011

Ok. As you reported it, I consider it as working as expected, and I'm closing this bug as no action.

Paul, I meant that under TWiki 4.1.2, %TOPIC% and %WEB% were expanded in the found topic context. Now, either they're not expanded, and therefore expanded in the search topic context, or they're expanded alongside all other variables (with the expandvariables parameter).
