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