• Performing a fuzzy search may retrieve terms with similar spellings: su sai ky tang xa hoi. hieu va ((cam duc) OR (pham duc)) manh hanh ((phan cua) or (nhan cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sai ky tang xa hoi. hieu va ((cam duc) OR (pham duc)) manh hanh ((phan cua) OR (nhan cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sai ky tang xa hoi. hieu va ((cam duc) OR (pham duc)) manh hanh ((phan cua) or (nhan cua)) tre".
• Adding a wildcard symbol may retrieve word variants: su sai ky tang xa hoi. hieu va ((cam duc) OR (pham duc)) manh hanh ((phan cua) or (nhan cua)) tre*.
