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