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