• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wan yan) OR (wai yan))) OR (((yang xi) OR (yang yi)))) zhang xin fan xing jin resting state ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wan yan) OR (wai yan))) or (((yang xi) or (yang yi)))) zhang xin fan xing jin resting state ;~".
• Adding a wildcard symbol may retrieve word variants: ((((wan yan) OR (wai yan))) or (((yang xi) or (yang yi)))) zhang xin fan xing jin resting state ;*.
