• Performing a fuzzy search may retrieve terms with similar spellings: su xac ((ky tang) or (ky dang)) xa hoi. hieu ve cam duc van anh ((noi cua) OR (moi cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su xac ((ky tang) OR (ky dang)) xa hoi. hieu ve cam duc van anh ((noi cua) OR (moi cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su xac ((ky tang) or (ky dang)) xa hoi. hieu ve cam duc van anh ((noi cua) OR (moi cua)) te".
• Adding a wildcard symbol may retrieve word variants: su xac ((ky tang) or (ky dang)) xa hoi. hieu ve cam duc van anh ((noi cua) OR (moi cua)) te*.
