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