• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang kang) OR (wang yanling)) ((than china) OR (wuhan china)) dan yang jin dang hari ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang kang) or (wang yanling)) ((than china) OR (wuhan china)) dan yang jin dang hari ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang kang) or (wang yanling)) ((than china) OR (wuhan china)) dan yang jin dang hari ;*.
