• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((y quang) or (ly quang)) ca hoi. lieu va nam xuc ((va hanh) OR (va danh)) vi cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((y quang) OR (ly quang)) ca hoi. lieu va nam xuc ((va hanh) OR (va danh)) vi cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((y quang) or (ly quang)) ca hoi. lieu va nam xuc ((va hanh) OR (va danh)) vi cua viet".
• Adding a wildcard symbol may retrieve word variants: tu sach ((y quang) or (ly quang)) ca hoi. lieu va nam xuc ((va hanh) OR (va danh)) vi cua viet*.
