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