• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky ((lang van) OR (tang van)) hoi. thi van ((hac nuoc) or (hoc nuoc)) va hang di cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((lang van) OR (tang van)) hoi. thi van ((hac nuoc) OR (hoc nuoc)) va hang di cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((lang van) OR (tang van)) hoi. thi van ((hac nuoc) or (hoc nuoc)) va hang di cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((lang van) OR (tang van)) hoi. thi van ((hac nuoc) or (hoc nuoc)) va hang di cua tre*.
