1) you need to search in the correct field
By default, search[{{}}] look in both the tiddler title and content. There
is one tiddler, [[Transclusion Basic Usage]] that contains the literal
"{{}}".
However, regexp[{{}}] defaults to only the title field, and there are no
tiddler *titles* that include the curly braces, thus no results.
To apply a regexp filter on the tiddler content, you need specify the
desired field by writing regexp:text[...]
2) The documentation in http://tiddlywiki.com/#regexp%20Operator says this:

Thus, to run the filter you want, you can't use the Advanced Search/Filter
tab. Instead, you need to write something like this into a tiddler:
<$set name="pattern" value="{{[a-zA-Z0-9]*}}">
<<list-links "[regexp:text<pattern>]">>
</$set>
Hope this helps,
enjoy,
