• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky ((sang dai) OR (sang tai)) hoi. hieu su ((phat xuc) or (phat xuat)) va hanh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((sang dai) OR (sang tai)) hoi. hieu su ((phat xuc) OR (phat xuat)) va hanh vai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((sang dai) OR (sang tai)) hoi. hieu su ((phat xuc) or (phat xuat)) va hanh vai cua te".
• Adding a wildcard symbol may retrieve word variants: tu sac ky ((sang dai) OR (sang tai)) hoi. hieu su ((phat xuc) or (phat xuat)) va hanh vai cua te*.
