• If you are trying to use Boolean operators, they must be ALL CAPS: (("deposition disorders / therapy") OR ((("deglutition disorders / therapy") OR ("nutrition disorders / therapy")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"deposition disorders / therapy\") or (((\"deglutition disorders / therapy\") OR (\"nutrition disorders / therapy\"))))".
• Removing quotes may allow a broader search: (( deposition disorders / therapy ) or ((( deglutition disorders / therapy ) OR ( nutrition disorders / therapy )))).
• Adding a wildcard symbol may retrieve word variants: (("deposition disorders / therapy") or ((("deglutition disorders / therapy") OR ("nutrition disorders / therapy"))))*.
