Introduced in v5.1.18 Note that the subfilter operator was introduced in version 5.1.18 and is not available in earlier versions.

Tip

Literal filter parameters cannot contain square brackets but you can work around the issue by using a variable:

<$set name="myFilter" value="[tag[one]]">
<$list filter="[all[tiddlers]subfilter<myFilter>]">
...

Tip

Compare with the similar filter operator which runs a subfilter against each title, returning those titles that return a non-empty list (and discards the results of the subfilter)

The subfilter operator will act as a constructor whenever the filter defined by its parameter is a constructor. Otherwise, it will act as a modifier.
