• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach y) or (sach tu)) ((lang xa) OR (dang xay)) hoi. hieu va cao xuc ban thanh cap cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach y) OR (sach tu)) ((lang xa) OR (dang xay)) hoi. hieu va cao xuc ban thanh cap cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach y) or (sach tu)) ((lang xa) OR (dang xay)) hoi. hieu va cao xuc ban thanh cap cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sach y) or (sach tu)) ((lang xa) OR (dang xay)) hoi. hieu va cao xuc ban thanh cap cuu tre*.
