Item999: Nested search does not result nothing, resulting in displaying an unwanted header

If a simple SEARCH has a header parameter, the header is only shown when there are results.

If a SEARCH contains a nested $percntSEARCH{}$percnt, and that search does not return any results, the header is still displayed.

For example from Support web (modified to return no results for sure):

%SEARCH{
"   *\s*.*?"
topic="QuestionSubjectCategory"
web="Support"
type="regex"
multiple="on"
casesensitive="on"
nonoise="on"
header="---++ Answered but needs refactoring"
format="$percntSEARCH{ $quotQuestionForm.Status='XXXAnswered but needs refactoring' AND QuestionForm.Subject='$pattern(.*   \*\s*([^\n]*).*)'$quot excludetopic=$quotQuestionTemplate$quot web=$quotSupport$quot type=$quotquery$quot format=$quot   * [[$dollarweb.$dollartopic][$dollarformfield(TopicTitle)]]$quot order=$quotmodified$quot reverse=$quoton$quot nonoise=$quoton$quot header=$quot---+++ $pattern(.*   \*\s*([^\n]*).*)$quot}$percnt"
}%

results in:

Answered but needs refactoring

Judging from what I see in http://trunk.foswiki.org/bin/view/Tasks/Item999, this is fixed. Arthur, can you close it if you agree.

I am still seeing the header while there is no search result.

Oh right, sorry, I misread the report. Sven, anything you can do, or are we stuck with this behaviour?

-- CrawfordCurrie - 07 Jun 2010

this cannot be a bug. the outer SEARCH has found a result, which is why the inner $percentSEARCH is triggered - which also means that the outer header should be displayed.

IMO, there is no (current or consistent) way that the outer SEARCH should modify its behavior based on what happens inside its format

its the same as

SEARCH{
   "..."
   header="got something.."
   format="$formfield(not_there)"

in which case the header is also displayed.

OK, then I guess we have to have confidence in your convictions and no-action it.
