Wow, I didn't realize search had changed so much. I really need to pay
attention to those release notes.
The five laws of concatenation, which I just made up:
Wikitext can't eat Wikitext
Wikitext can't eat Widgets
Widgets can't eat Widgets
Widgets CAN eat Wikitext.
Wikify can sometimes bend laws 1 through 3
The following version may be too distant from what you wanted, but might
serve as a start. It did work in my quick test:
\define ppfilter(pp) [tag[data_page]search:text:literal["father":
"{{!!parent_page}}"]]
<$wikify name=search text=<<ppfilter>>>
Variable: <<search>>
<$list filter=<<search>> >
* Search Result: {{!!title}}
</$list>
</$wikify>
