• If you are trying to use Boolean operators, they must be ALL CAPS: thuat san ty nang x hoi. hieu ((van cham) OR (van chat)) soc van ((thanh va) OR (hanh va)) hoa viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat san ty nang x hoi. hieu ((van cham) OR (van chat)) soc van ((thanh va) or (hanh va)) hoa viet".
• Adding a wildcard symbol may retrieve word variants: thuat san ty nang x hoi. hieu ((van cham) OR (van chat)) soc van ((thanh va) or (hanh va)) hoa viet*.
