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