• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach va) OR (sach xa)) lang xa hoi. hieu ((va cai) or (va cac)) xuc van hanh di cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach va) OR (sach xa)) lang xa hoi. hieu ((va cai) OR (va cac)) xuc van hanh di cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach va) OR (sach xa)) lang xa hoi. hieu ((va cai) or (va cac)) xuc van hanh di cua te".
• Adding a wildcard symbol may retrieve word variants: te ((sach va) OR (sach xa)) lang xa hoi. hieu ((va cai) or (va cac)) xuc van hanh di cua te*.
