• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((thue nang) or (thien dang)) xa hoi. lieu va chat duc va hanh di ((cua te) OR (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((thue nang) OR (thien dang)) xa hoi. lieu va chat duc va hanh di ((cua te) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((thue nang) or (thien dang)) xa hoi. lieu va chat duc va hanh di ((cua te) OR (cua tu))".
• Adding a wildcard symbol may retrieve word variants: te sach ((thue nang) or (thien dang)) xa hoi. lieu va chat duc va hanh di ((cua te) OR (cua tu))*.
