• Performing a fuzzy search may retrieve terms with similar spellings: tu sai ky ((nang ma) OR (nang cao)) hoi. lieu ha nam thuc xa hanh ((tai cuu) or (thai cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ky ((nang ma) OR (nang cao)) hoi. lieu ha nam thuc xa hanh ((tai cuu) OR (thai cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ky ((nang ma) OR (nang cao)) hoi. lieu ha nam thuc xa hanh ((tai cuu) or (thai cua)) tre".
• Adding a wildcard symbol may retrieve word variants: tu sai ky ((nang ma) OR (nang cao)) hoi. lieu ha nam thuc xa hanh ((tai cuu) or (thai cua)) tre*.
