• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (wang yan)) ((kyi a) OR (kai fa)) brain using min dang hari ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) OR (wang yan)) ((kyi a) or (kai fa)) brain using min dang hari ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) OR (wang yan)) ((kyi a) or (kai fa)) brain using min dang hari ;*.
