• If you are trying to use Boolean operators, they must be ALL CAPS: (((("computer apple. in life science") OR ((("computer appl. in life science") OR ("computer apps. in life science"))))) OR ("computer apple. in fire science")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"computer apple. in life science\") or (((\"computer appl. in life science\") OR (\"computer apps. in life science\"))))) or (\"computer apple. in fire science\"))".
• Removing quotes may allow a broader search: (((( computer apple. in life science ) or ((( computer appl. in life science ) OR ( computer apps. in life science ))))) or ( computer apple. in fire science )).
• Adding a wildcard symbol may retrieve word variants: (((("computer apple. in life science") or ((("computer appl. in life science") OR ("computer apps. in life science"))))) or ("computer apple. in fire science"))*.
