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