• Performing a fuzzy search may retrieve terms with similar spellings: tu sai ky ((nang co) OR (nang doc)) hoc. thien van ((cham soc) or (chat xuc)) va thanh lap cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ky ((nang co) OR (nang doc)) hoc. thien van ((cham soc) OR (chat xuc)) va thanh lap cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ky ((nang co) OR (nang doc)) hoc. thien van ((cham soc) or (chat xuc)) va thanh lap cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu sai ky ((nang co) OR (nang doc)) hoc. thien van ((cham soc) or (chat xuc)) va thanh lap cuu tre*.
