• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky dang xay hoi. hieu ((ve cam) OR (ve cac)) xuc ban lanh hai ((cua triet) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky dang xay hoi. hieu ((ve cam) OR (ve cac)) xuc ban lanh hai ((cua triet) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky dang xay hoi. hieu ((ve cam) OR (ve cac)) xuc ban lanh hai ((cua triet) or (cuu tre))*".
