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