• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ((y nang) OR (ky nang)) xa hoi. hieu ve cam tuc va xanh ((di cua) or (de cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ((y nang) OR (ky nang)) xa hoi. hieu ve cam tuc va xanh ((di cua) OR (de cua)) triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ((y nang) OR (ky nang)) xa hoi. hieu ve cam tuc va xanh ((di cua) or (de cua)) triet*".
