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