• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty ((xang x) OR (nang x)) hoi. hieu ((le nam) OR (le na)) truc va thanh vinh cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty ((xang x) or (nang x)) hoi. hieu ((le nam) OR (le na)) truc va thanh vinh cuu tre".
• Adding a wildcard symbol may retrieve word variants: thu sach ty ((xang x) or (nang x)) hoi. hieu ((le nam) OR (le na)) truc va thanh vinh cuu tre*.
