• If you are trying to use Boolean operators, they must be ALL CAPS: %((((((((byquality control) OR (quality control))) OR (qouality control))) OR (quality controls))) OR (forquality control))%((11 reliability) OR (9 reliability))%22 safety AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((((((((byquality control) OR (quality control))) or (qouality control))) or (quality controls))) or (forquality control))%((11 reliability) or (9 reliability))%22 safety and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((((((((byquality control) OR (quality control))) or (qouality control))) or (quality controls))) or (forquality control))%((11 reliability) or (9 reliability))%22 safety and risk%22*.
