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