Hi Steve
You can only use transclusion within filters to transclude an entire
operand. With the syntax you've used the curly braces would be considered
part of the regexp.
So you can do something like this:
<$list filter="[!is[system]tags[]regexp{$:/temp/search}]">
You can also use variables:
\define search-string()
(?i)($(search-term)$)
\end
<$set name="search-term" value="searchme">
<$list filter="[!is[system]tags[]regexp<search-string>]"/>
</$set>
However, not that the search term doesn't get "regexp encoded" so any
special regexp characters will not be searched for literally.
Best wishes
Jeremy
