• Performing a fuzzy search may retrieve terms with similar spellings: thuat sach ty dang xay hoi. ((hieu ve) or (lieu va)) cam xuc van ((hanh tai) OR (han tai)) cho tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach ty dang xay hoi. ((hieu ve) OR (lieu va)) cam xuc van ((hanh tai) OR (han tai)) cho tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach ty dang xay hoi. ((hieu ve) or (lieu va)) cam xuc van ((hanh tai) OR (han tai)) cho tre".
• Adding a wildcard symbol may retrieve word variants: thuat sach ty dang xay hoi. ((hieu ve) or (lieu va)) cam xuc van ((hanh tai) OR (han tai)) cho tre*.
