• Performing a fuzzy search may retrieve terms with similar spellings: thu sai ky ((nang xa) OR (nang ma)) hoi. hieu van hau xuc tuan anh vi ((xu tren) or (tu tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sai ky ((nang xa) OR (nang ma)) hoi. hieu van hau xuc tuan anh vi ((xu tren) OR (tu tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sai ky ((nang xa) OR (nang ma)) hoi. hieu van hau xuc tuan anh vi ((xu tren) or (tu tren))".
• Adding a wildcard symbol may retrieve word variants: thu sai ky ((nang xa) OR (nang ma)) hoi. hieu van hau xuc tuan anh vi ((xu tren) or (tu tren))*.
