• Performing a fuzzy search may retrieve terms with similar spellings: ((te sach) or (su sach)) ky nang o hai. thien van cau xuc ((van thanh) OR (van tuan)) tai cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (su sach)) ky nang o hai. thien van cau xuc ((van thanh) OR (van tuan)) tai cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (su sach)) ky nang o hai. thien van cau xuc ((van thanh) OR (van tuan)) tai cua tu".
• Adding a wildcard symbol may retrieve word variants: ((te sach) or (su sach)) ky nang o hai. thien van cau xuc ((van thanh) OR (van tuan)) tai cua tu*.
