• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty hoang van hoi. hieu van ((cam luc) OR (cam xuc)) va hanh ((hai cua) OR (dai cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty hoang van hoi. hieu van ((cam luc) OR (cam xuc)) va hanh ((hai cua) or (dai cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: te sach ty hoang van hoi. hieu van ((cam luc) OR (cam xuc)) va hanh ((hai cua) or (dai cua)) tre*.
