• If you are trying to use Boolean operators, they must be ALL CAPS: thuat san day nang x hoi. hieu ((ve cham) OR (((vu cham) OR (va cham)))) thuc va hanh vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat san day nang x hoi. hieu ((ve cham) or (((vu cham) OR (va cham)))) thuc va hanh vai cua tre*".
