Perhaps you should try some spelling variations:
forquality control » quality control, byquality control, qouality control
_quality control » quality control, byquality control, quality controls
ic reliability » 2 reliability, 5 reliability, 8 reliability
1 reliability » 3 reliability, 2 reliability, 5 reliability
9 reliability » 3 reliability, 2 reliability, 5 reliability
22 safety » 2 safety, 12 safety, a 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: %((_quality control) OR (forquality control))%((1 reliability) OR (((ic reliability) OR (9 reliability))))%((22 safety) OR (_ safety)) AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((_quality control) or (forquality control))%((1 reliability) or (((ic reliability) OR (9 reliability))))%((22 safety) or (_ safety)) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((_quality control) or (forquality control))%((1 reliability) or (((ic reliability) OR (9 reliability))))%((22 safety) or (_ safety)) and risk%22*.
