Perhaps you should try some spelling variations:
forquality control » quality control, _quality control, qouality control
byquality control » quality control, _quality control, quality controls
ic reliability » 7 reliability, 8 reliability, 11 reliability
4 reliability » 3 reliability
5 reliability » 3 reliability
2 reliability » 3 reliability
2c safety » 2 safety, 22 safety, 23 safety
3 safety » 5 safety, 4 safety

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: %((byquality control) OR (forquality control))%((4 reliability) OR (((((ic reliability) OR (5 reliability))) OR (2 reliability))))%((2c safety) OR (3 safety)) AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((byquality control) OR (forquality control))%((4 reliability) or (((((ic reliability) or (5 reliability))) or (2 reliability))))%((2c safety) or (3 safety)) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((byquality control) OR (forquality control))%((4 reliability) or (((((ic reliability) or (5 reliability))) or (2 reliability))))%((2c safety) or (3 safety)) and risk%22*.
