To construct a parameter value (i.e., the value following the "href="
syntax), you need to use a "filtered transclusion", like this:
<a href={{{ [{Search}addsuffix[.com]] }}}> link 1</a>
<a href={{{ [{Search}addsuffix[.co.uk]] }}}> link 2</a>
<a href={{{ [{Search}addsuffix[.fr]] }}}> link 3</a>
Notes:
1) The filtered transclusion syntax is contained within tripled curly
braces: {{{ filter }}}
2) The filter syntax itself is contained inside a matched pair of single
square brackets: [...]
3) To reference the text content of a tiddler within a filter, use *single*
curly braces: {TiddlerName}
4) To append the desired literal text (i.e., ".com", ".co.uk", etc.) use
the addsuffix[...] operator
