Perhaps you should try some spelling variations:

using control » losing control, dosing control, pumping control
net savings » cost savings, term savings, fuel savings
control di » control de, control do, control del
calling a » calling _, filling a
selling a » selling _
wen name » den namen, dein name, mein name

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wen name ((calling a) OR (selling a)) net savings using control di ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wen name ((calling a) OR (selling a)) net savings using control di ;*".
