ignore words overflow

The module fails if you put a few words (over few chars) in the "ignore Leading Words".
In fact

$replace = array(
"SELECT DISTINCT $myfield FROM ",
" ORDER BY $myfield"

assigns an overflow string to the array that you are going to use as key fetching the query
$item->{$myfield}

$myfield become too big to be used as key.

So, here you have a patch that renames the field name:
$replace = array(
"SELECT DISTINCT $myfield as myfield FROM ",
" ORDER BY myfield",
"",
);

and use it as key.
Let me know...
Thanks
