• Performing a fuzzy search may retrieve terms with similar spellings: ((vu sach) or (vu bach)) ly lang xa hoi. hieu qua cam tuc van dinh ((luc cua) OR (luc nua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (vu bach)) ly lang xa hoi. hieu qua cam tuc van dinh ((luc cua) OR (luc nua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) or (vu bach)) ly lang xa hoi. hieu qua cam tuc van dinh ((luc cua) OR (luc nua)) te".
• Adding a wildcard symbol may retrieve word variants: ((vu sach) or (vu bach)) ly lang xa hoi. hieu qua cam tuc van dinh ((luc cua) OR (luc nua)) te*.
