• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ((ha ke) OR (kha ke)) giai ((((hoan hoang) or (tuan hoang))) or (quan hoang)) minh~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ((ha ke) OR (kha ke)) giai ((((hoan hoang) OR (tuan hoang))) OR (quan hoang)) minh.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ((ha ke) OR (kha ke)) giai ((((hoan hoang) or (tuan hoang))) or (quan hoang)) minh".
