Perhaps you should try some spelling variations:
_quality control » quality control, byquality control, quality controls
24 reliability » 2.4 reliability, 14 reliability, 20 reliability
ic reliability » 3 reliability, 5 reliability, 7 reliability
9 reliability » 3 reliability, 5 reliability
4 reliability » 3 reliability, 5 reliability
2 reliability » 3 reliability, 5 reliability
2c safety » 2 safety, 22 safety, 23 safety

Try widening your search to All Fields.

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%((24 reliability) OR (((((ic reliability) OR (((9 reliability) OR (4 reliability))))) OR (2 reliability))))%((2c safety) OR (_ safety)) AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%_quality control%((24 reliability) or (((((ic reliability) or (((9 reliability) OR (4 reliability))))) or (2 reliability))))%((2c safety) or (_ safety)) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %_quality control%((24 reliability) or (((((ic reliability) or (((9 reliability) OR (4 reliability))))) or (2 reliability))))%((2c safety) or (_ safety)) and risk%22*.
