• Performing a fuzzy search may retrieve terms with similar spellings: te san ky nang cao hoc. thien van nam luc van ((thanh ve) or (((hanh va) OR (hanh vi)))) cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te san ky nang cao hoc. thien van nam luc van ((thanh ve) OR (((hanh va) OR (hanh vi)))) cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te san ky nang cao hoc. thien van nam luc van ((thanh ve) or (((hanh va) OR (hanh vi)))) cua viet".
• Adding a wildcard symbol may retrieve word variants: te san ky nang cao hoc. thien van nam luc van ((thanh ve) or (((hanh va) OR (hanh vi)))) cua viet*.
