• Performing a fuzzy search may retrieve terms with similar spellings: ((thu sach) OR (tu sach)) ty nang xa hoi. hieu va cam xuc ban anh ((hai cua) or (hoi cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (tu sach)) ty nang xa hoi. hieu va cam xuc ban anh ((hai cua) OR (hoi cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) OR (tu sach)) ty nang xa hoi. hieu va cam xuc ban anh ((hai cua) or (hoi cua)) te".
• Adding a wildcard symbol may retrieve word variants: ((thu sach) OR (tu sach)) ty nang xa hoi. hieu va cam xuc ban anh ((hai cua) or (hoi cua)) te*.
