- If you are trying to use Boolean operators, they must be ALL CAPS: (("operational systems") OR ((("relational systems") OR ("functional systems")))).
- The words AND, OR and NOT may confuse the search; try adding quotes: "((\"operational systems\") or (((\"relational systems\") OR (\"functional systems\"))))".
- Removing quotes may allow a broader search: (( operational systems ) or ((( relational systems ) OR ( functional systems )))).
- Adding a wildcard symbol may retrieve word variants: (("operational systems") or ((("relational systems") OR ("functional systems"))))*.
