• If you are trying to use Boolean operators, they must be ALL CAPS: (((("yu wang cheng _ she ji song shu") OR ("yu fang cheng _ she ji song shu"))) OR ("tu ling chen xi she ji kyung soo")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"yu wang cheng _ she ji song shu\") OR (\"yu fang cheng _ she ji song shu\"))) or (\"tu ling chen xi she ji kyung soo\"))".
• Removing quotes may allow a broader search: (((( yu wang cheng _ she ji song shu ) OR ( yu fang cheng _ she ji song shu ))) or ( tu ling chen xi she ji kyung soo )).
• Adding a wildcard symbol may retrieve word variants: (((("yu wang cheng _ she ji song shu") OR ("yu fang cheng _ she ji song shu"))) or ("tu ling chen xi she ji kyung soo"))*.
