• If you are trying to use Boolean operators, they must be ALL CAPS: (( health ((science network) OR (sciences network)) systems report ) OR ((( health guidance network synthesis report ) OR ((( health guide network synthesis report ) OR ( health grid network synthesis report )))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( health ((science network) OR (sciences network)) systems report ) or ((( health guidance network synthesis report ) or ((( health guide network synthesis report ) or ( health grid network synthesis report ))))))".
• Adding a wildcard symbol may retrieve word variants: (( health ((science network) OR (sciences network)) systems report ) or ((( health guidance network synthesis report ) or ((( health guide network synthesis report ) or ( health grid network synthesis report ))))))*.
