• Performing a fuzzy search may retrieve terms with similar spellings: hoc anh tu nang cho hoc. hieu ve ((cac vuc) or (cac nuoc)) ban ((hanh di) OR (hang di)) cua cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc anh tu nang cho hoc. hieu ve ((cac vuc) OR (cac nuoc)) ban ((hanh di) OR (hang di)) cua cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc anh tu nang cho hoc. hieu ve ((cac vuc) or (cac nuoc)) ban ((hanh di) OR (hang di)) cua cau*".
