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