• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ky) OR (sach ty)) dang ma hoi. hieu ve cam ((xuc va) or (truc va)) hanh dai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sach ty)) dang ma hoi. hieu ve cam ((xuc va) OR (truc va)) hanh dai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sach ty)) dang ma hoi. hieu ve cam ((xuc va) or (truc va)) hanh dai cuu tre".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) OR (sach ty)) dang ma hoi. hieu ve cam ((xuc va) or (truc va)) hanh dai cuu tre*.
