• Performing a fuzzy search may retrieve terms with similar spellings: thu sac ky ((nang xa) OR (nang ma)) hoi. hieu ve cac lo van anh ((via cua) or (gian cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky ((nang xa) OR (nang ma)) hoi. hieu ve cac lo van anh ((via cua) OR (gian cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky ((nang xa) OR (nang ma)) hoi. hieu ve cac lo van anh ((via cua) or (gian cua)) te".
• Adding a wildcard symbol may retrieve word variants: thu sac ky ((nang xa) OR (nang ma)) hoi. hieu ve cac lo van anh ((via cua) or (gian cua)) te*.
