• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((sach ky) OR (sac ky)) ((tang xa) or (tang ma)) hoi. hieu va cham xuc ban hanh vi cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((sach ky) OR (sac ky)) ((tang xa) OR (tang ma)) hoi. hieu va cham xuc ban hanh vi cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((sach ky) OR (sac ky)) ((tang xa) or (tang ma)) hoi. hieu va cham xuc ban hanh vi cua tu".
• Adding a wildcard symbol may retrieve word variants: hoc ((sach ky) OR (sac ky)) ((tang xa) or (tang ma)) hoi. hieu va cham xuc ban hanh vi cua tu*.
