• Performing a fuzzy search may retrieve terms with similar spellings: hoc sach ((y nang) OR (ly nang)) xa hoi. hieu ((ve cam) or (vu cham)) duc va thanh binh cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc sach ((y nang) OR (ly nang)) xa hoi. hieu ((ve cam) OR (vu cham)) duc va thanh binh cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc sach ((y nang) OR (ly nang)) xa hoi. hieu ((ve cam) or (vu cham)) duc va thanh binh cuu tre".
• Adding a wildcard symbol may retrieve word variants: hoc sach ((y nang) OR (ly nang)) xa hoi. hieu ((ve cam) or (vu cham)) duc va thanh binh cuu tre*.
