Sure--add a control named "group" to the search form.  If one is
present, then PmWiki limits its search to the value of this control
(however, someone can still search a different group by specifying
the group name as part of the search string).

For example, change the search markup output format in local.php with

    $SearchTagFmt = "<form action='\$PageUrl' method='get'><input 
      type='hidden' name='group' value='\$Group' /><input 
      type='hidden' name='action' value='search' /><input type='text' 
      name='text' value='' size='40' /><input type='submit' 
      value='Search' /></form>";

The only difference between this and the default search tag is the 
addition of the type='hidden' name='group' input element.

There's nothing that says the group control has to be a 'hidden' control,
it could also be specified by a checkbox, radio button, selection, text, 
or textarea control.

At present there's no way to search a set of groups; you can either search
a single group or all of them.  However, it wouldn't be too difficult for
me to modify search.php to allow multiple groups if that's needed.

I've also added this information to the Cookbook at
