Perhaps you should try some spelling variations:
22quality control » quality control, _quality control, byquality control
10 reliability » 3 reliability, 5 reliability, 2 reliability
ic reliability » 5 reliability, 2 reliability, 7 reliability
9 reliability » 3 reliability, 5 reliability, 2 reliability
safety » samety
safe » same

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%((10 reliability) OR (((ic reliability) OR (9 reliability))))%((a safety) OR (a safe)) AND risk%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22quality control%((10 reliability) or (((ic reliability) or (9 reliability))))%((a safety) OR (a safe)) and risk%22*".
