                }
                $criteria->add($allSubCriterias); // added to fix bug

        There are two bugs in the above code: all subcrits need to be added to the main
        criteria as a group, so it was a bug to have them added one at a time as they
        were, since the nesting of the () in the rendered where clause is incorrect also
        there was a bug which caused only the first and last items in the query array to
        be processed, and the last item would be processed multiple times.  ie: terms
        "green, orange, black" resulted in a search for "green, black, black" -- this
        "bug" was introduced with php 4.4.0 (and some version of 5 as well) after a
        change in how objects are managed in memory or something like that.
        The fix is to specifically unset the $subCriteria object at the end of each
        iteration of the loop. The same bug hit Liase, Formulaire and Formulize.
        You can see the structure of the query by printing the output of $criteria's
        render or renderWhere method ( ie: print $criteria->renderWhere(); )
        However, the whole approach to handling queries has been changed, so the above
        code is unused.  It is included here for reference with regard to the bugs
        mentioned above.
        With custom forms, because a multi term query using AND could have some terms
        match only custom form fields and other terms match only native Wfdownloads
        fields, each term must be evaluated independently,
        across both modules, and then if an AND operator is in effect, the intersection
        of the results is returned.  If OR is in effect, then all results are returned.
