• Performing a fuzzy search may retrieve terms with similar spellings: toc sach ((y lang) OR (_ lang)) xa hoi. thien van tham nuoc ((va hanh) or (va danh)) vinh cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach ((y lang) OR (_ lang)) xa hoi. thien van tham nuoc ((va hanh) OR (va danh)) vinh cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ((y lang) OR (_ lang)) xa hoi. thien van tham nuoc ((va hanh) or (va danh)) vinh cuu tre".
• Adding a wildcard symbol may retrieve word variants: toc sach ((y lang) OR (_ lang)) xa hoi. thien van tham nuoc ((va hanh) or (va danh)) vinh cuu tre*.
