• Performing a fuzzy search may retrieve terms with similar spellings: tu san ky ((dang lai) or (dang loai)) hoi. hieu ((su chat) OR (su phat)) va va hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ky ((dang lai) OR (dang loai)) hoi. hieu ((su chat) OR (su phat)) va va hanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ky ((dang lai) or (dang loai)) hoi. hieu ((su chat) OR (su phat)) va va hanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: tu san ky ((dang lai) or (dang loai)) hoi. hieu ((su chat) OR (su phat)) va va hanh vi cua te*.
