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