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