Perhaps you should try some spelling variations:
22quality control » quality control, _quality control, byquality control
2c reliability » 20 reliability, 24 reliability, 29 reliability
ic reliability » 5 reliability, 7 reliability, 8 reliability
2 reliability » 3 reliability, 5 reliability

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

• If you are trying to use Boolean operators, they must be ALL CAPS: %22quality control%((2c reliability) OR (((ic reliability) OR (2 reliability))))%_ safety AND risk%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22quality control%((2c reliability) or (((ic reliability) OR (2 reliability))))%_ safety and risk%22*".
