• If you are trying to use Boolean operators, they must be ALL CAPS: (((("Health defence network synthesis report") OR ("Health defense network synthesis report"))) OR ("health dence network systems report")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"Health defence network synthesis report\") OR (\"Health defense network synthesis report\"))) or (\"health dence network systems report\"))".
• Removing quotes may allow a broader search: (((( Health defence network synthesis report ) OR ( Health defense network synthesis report ))) or ( health dence network systems report )).
• Adding a wildcard symbol may retrieve word variants: (((("Health defence network synthesis report") OR ("Health defense network synthesis report"))) or ("health dence network systems report"))*.
