• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach tu) OR (sach thu)) nang ma hoi. hieu ve ((cac xuc) or (cac nuoc)) van hanh vai cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach tu) OR (sach thu)) nang ma hoi. hieu ve ((cac xuc) OR (cac nuoc)) van hanh vai cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach tu) OR (sach thu)) nang ma hoi. hieu ve ((cac xuc) or (cac nuoc)) van hanh vai cua tu".
• Adding a wildcard symbol may retrieve word variants: te ((sach tu) OR (sach thu)) nang ma hoi. hieu ve ((cac xuc) or (cac nuoc)) van hanh vai cua tu*.
