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