• If you are trying to use Boolean operators, they must be ALL CAPS: wang binh tran hua ren yang ((((jin song) OR (john song))) OR (kim song)) sam ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang binh tran hua ren yang ((((jin song) OR (john song))) or (kim song)) sam ;~".
• Adding a wildcard symbol may retrieve word variants: wang binh tran hua ren yang ((((jin song) OR (john song))) or (kim song)) sam ;*.
