• Performing a fuzzy search may retrieve terms with similar spellings: ((toc sach) OR (hoc sach)) 2 lang xa hoi. hieu ((va cam) or (va cac)) xuc va thanh doi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((toc sach) OR (hoc sach)) 2 lang xa hoi. hieu ((va cam) OR (va cac)) xuc va thanh doi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((toc sach) OR (hoc sach)) 2 lang xa hoi. hieu ((va cam) or (va cac)) xuc va thanh doi cua te".
• Adding a wildcard symbol may retrieve word variants: ((toc sach) OR (hoc sach)) 2 lang xa hoi. hieu ((va cam) or (va cac)) xuc va thanh doi cua te*.
