• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty nang mai hoi. hieu va chat ((((xuc va) OR (tuc va))) OR (luc va)) danh ca cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty nang mai hoi. hieu va chat ((((xuc va) OR (tuc va))) or (luc va)) danh ca cua tre".
• Adding a wildcard symbol may retrieve word variants: thu sach ty nang mai hoi. hieu va chat ((((xuc va) OR (tuc va))) or (luc va)) danh ca cua tre*.
