• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ky nang co hoi. lieu va cam ((xuc va) OR (tuc va)) dung ((tai cua) or (thai cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky nang co hoi. lieu va cam ((xuc va) OR (tuc va)) dung ((tai cua) OR (thai cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky nang co hoi. lieu va cam ((xuc va) OR (tuc va)) dung ((tai cua) or (thai cua)) triet".
• Adding a wildcard symbol may retrieve word variants: thu sach ky nang co hoi. lieu va cam ((xuc va) OR (tuc va)) dung ((tai cua) or (thai cua)) triet*.
