• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty ((hang xa) OR (hang ca)) hoi. ((lieu va) or (hieu va)) cau luc ban hanh vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty ((hang xa) OR (hang ca)) hoi. ((lieu va) OR (hieu va)) cau luc ban hanh vi cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty ((hang xa) OR (hang ca)) hoi. ((lieu va) or (hieu va)) cau luc ban hanh vi cuu tre*".
