• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky ((anh xay) OR (anh hay)) hoi. hieu ve cam xuc ban thanh hai ((dua tren) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky ((anh xay) OR (anh hay)) hoi. hieu ve cam xuc ban thanh hai ((dua tren) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky ((anh xay) OR (anh hay)) hoi. hieu ve cam xuc ban thanh hai ((dua tren) or (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: su sach ky ((anh xay) OR (anh hay)) hoi. hieu ve cam xuc ban thanh hai ((dua tren) or (cuu tre))*.
