• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sac ly) or (sac ky)) van tay ho. hieu van cam xuc ((xa hang) OR (va hang)) dieu cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sac ly) OR (sac ky)) van tay ho. hieu van cam xuc ((xa hang) OR (va hang)) dieu cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sac ly) or (sac ky)) van tay ho. hieu van cam xuc ((xa hang) OR (va hang)) dieu cua tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sac ly) or (sac ky)) van tay ho. hieu van cam xuc ((xa hang) OR (va hang)) dieu cua tre*.
