• Performing a fuzzy search may retrieve terms with similar spellings: vu khanh ky nang xa hoi. hieu ((van hai) OR (van phan)) truc ((va hanh) or (van hanh)) vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu khanh ky nang xa hoi. hieu ((van hai) OR (van phan)) truc ((va hanh) OR (van hanh)) vi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu khanh ky nang xa hoi. hieu ((van hai) OR (van phan)) truc ((va hanh) or (van hanh)) vi cua tre*".
