• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ((y dang) OR (ky dang)) xay hoi. hieu ve coc luc va danh du ((cua te) or (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ((y dang) OR (ky dang)) xay hoi. hieu ve coc luc va danh du ((cua te) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ((y dang) OR (ky dang)) xay hoi. hieu ve coc luc va danh du ((cua te) or (cua tu))".
• Adding a wildcard symbol may retrieve word variants: vu sach ((y dang) OR (ky dang)) xay hoi. hieu ve coc luc va danh du ((cua te) or (cua tu))*.
