• Performing a fuzzy search may retrieve terms with similar spellings: su sach y ((lang ha) OR (long ha)) hoi. hieu ((van dam) or (van nam)) xuc va thanh va cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y ((lang ha) OR (long ha)) hoi. hieu ((van dam) OR (van nam)) xuc va thanh va cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y ((lang ha) OR (long ha)) hoi. hieu ((van dam) or (van nam)) xuc va thanh va cua triet".
• Adding a wildcard symbol may retrieve word variants: su sach y ((lang ha) OR (long ha)) hoi. hieu ((van dam) or (van nam)) xuc va thanh va cua triet*.
