• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((v dang) OR (vu dang)) xay 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 ((v dang) OR (vu dang)) xay 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 ((v dang) OR (vu dang)) xay hoi. hieu ((va cai) or (va cac)) xuc van hanh di cua te".
• Adding a wildcard symbol may retrieve word variants: te sach ((v dang) OR (vu dang)) xay hoi. hieu ((va cai) or (va cac)) xuc van hanh di cua te*.
