• Performing a fuzzy search may retrieve terms with similar spellings: thu sach tay dang xay hoi. hieu van cam xuc va ((manh hai) or (minh hai)) ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach tay dang xay hoi. hieu van cam xuc va ((manh hai) OR (minh hai)) ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach tay dang xay hoi. hieu van cam xuc va ((manh hai) or (minh hai)) ((cua tre) OR (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: thu sach tay dang xay hoi. hieu van cam xuc va ((manh hai) or (minh hai)) ((cua tre) OR (cuu tre))*.
