• Performing a fuzzy search may retrieve terms with similar spellings: so ((sach v) or (((sach ha) OR (sach xa)))) nang doc hoi. thien van hac xuc va hanh hai chu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so ((sach v) OR (((sach ha) OR (sach xa)))) nang doc hoi. thien van hac xuc va hanh hai chu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so ((sach v) or (((sach ha) OR (sach xa)))) nang doc hoi. thien van hac xuc va hanh hai chu tre*".
