fix: server throws "undefined variable" errors for $folder and $searchTerm

[cfreitag]

In line 67, it is possible that $folder is undefinded if the variable search_area isn't set and the if clause in line 62 is never entered. To prevent this, define $folder = array(); before it is first used, e. g. after line 57.

In line 171 the variable passed to public function isLowValueWord should be $searchTerm, not $word for the function to work.

See revised version of plugin attached.
