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