• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky nang xa hoi. hieu ((va cham) or (va chat)) tuc ((va hanh) OR (van hanh)) tai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang xa hoi. hieu ((va cham) OR (va chat)) tuc ((va hanh) OR (van hanh)) tai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang xa hoi. hieu ((va cham) or (va chat)) tuc ((va hanh) OR (van hanh)) tai cua tre".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang xa hoi. hieu ((va cham) or (va chat)) tuc ((va hanh) OR (van hanh)) tai cua tre*.
