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