• Performing a fuzzy search may retrieve terms with similar spellings: so sach ky ((nang xa) OR (nang x)) hoi. hieu ve cac xuc cam ((gan vi) or (dan va)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ky ((nang xa) OR (nang x)) hoi. hieu ve cac xuc cam ((gan vi) OR (dan va)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ky ((nang xa) OR (nang x)) hoi. hieu ve cac xuc cam ((gan vi) or (dan va)) cua tre".
• Adding a wildcard symbol may retrieve word variants: so sach ky ((nang xa) OR (nang x)) hoi. hieu ve cac xuc cam ((gan vi) or (dan va)) cua tre*.
