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