• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky ((nang ma) OR (nang cao)) hoi. hieu ve cham soc va thanh vien ((cua tu) OR (cua su)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky ((nang ma) OR (nang cao)) hoi. hieu ve cham soc va thanh vien ((cua tu) or (cua su))".
• Adding a wildcard symbol may retrieve word variants: te sac ky ((nang ma) OR (nang cao)) hoi. hieu ve cham soc va thanh vien ((cua tu) or (cua su))*.
