Perhaps you should try some spelling variations:
quality controls » qualite controle, quality concepts
24 reliability » 2.4 reliability, 2 reliability, 4 reliability
ic reliability » 5 reliability, 2 reliability, 7 reliability
3 reliability » 5 reliability
2 safety » 5 safety, 4 safety, 3 safety
a safety » a safe

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 controls) OR (quality control))%((((24 reliability) OR (3 reliability))) OR (ic reliability))%((2 safety) OR (a safety)) AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((quality controls) or (quality control))%((((24 reliability) or (3 reliability))) or (ic reliability))%((2 safety) OR (a safety)) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((quality controls) or (quality control))%((((24 reliability) or (3 reliability))) or (ic reliability))%((2 safety) OR (a safety)) and risk%22*.
