• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sach ty)) nang ma hoi. hieu ve cam xuc ban thanh ((tai cua) OR (thai cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) or (sach ty)) nang ma hoi. hieu ve cam xuc ban thanh ((tai cua) OR (thai cua)) tre".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) or (sach ty)) nang ma hoi. hieu ve cam xuc ban thanh ((tai cua) OR (thai cua)) tre*.
