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