Perhaps you should try some spelling variations:
quality controls » quality concepts
2c reliability » 2 reliability, 20 reliability, 24 reliability
2 safety » 5 safety, 4 safety, 3 safety
a safety » a safe

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