• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach kem) or (sach ty)) nang xa hoi. dieu hien hanh xuc may tich va ((huu tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach kem) OR (sach ty)) nang xa hoi. dieu hien hanh xuc may tich va ((huu tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach kem) or (sach ty)) nang xa hoi. dieu hien hanh xuc may tich va ((huu tre) OR (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: tu ((sach kem) or (sach ty)) nang xa hoi. dieu hien hanh xuc may tich va ((huu tre) OR (cuu tre))*.
