• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ky dang) OR (ky anh)) ((ma hoi) OR (mai hoi)). hieu van lam xuc va hanh thai cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ky dang) or (ky anh)) ((ma hoi) OR (mai hoi)). hieu van lam xuc va hanh thai cuu tre~".
• Adding a wildcard symbol may retrieve word variants: te sach ((ky dang) or (ky anh)) ((ma hoi) OR (mai hoi)). hieu van lam xuc va hanh thai cuu tre*.
