• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ((thu nang) OR (thi 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 ((thu nang) OR (thi 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 ((thu nang) OR (thi nang)) xa hoi. hieu va cam xuc ban anh ((hai cua) or (hoi cua)) te*.
