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