• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y nang) OR (((v nang) OR (va nang)))) xa hoi. hieu van chat tuc va hang hoi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y nang) or (((v nang) OR (va nang)))) xa hoi. hieu van chat tuc va hang hoi cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach ((y nang) or (((v nang) OR (va nang)))) xa hoi. hieu van chat tuc va hang hoi cua tre*.
