Bug: METASEARRCH default parameter doesn't work

The implementation looks for the search returning a result containing just whitespace. However the search uses a template, searchmeta, that may (as in the current case) contain default text so that the search never returns whitespace.

There really ought to be a better way to do this, probably involving changing searchWeb to take a formatting object instead of doing everything in that mega-function.
