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