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