• Performing a fuzzy search may retrieve terms with similar spellings: (( tiep can tam linh vuc. ) or ( tap ((((trinh lam) OR (trinh luat))) or (trinh lap)) minh duc. ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tiep can tam linh vuc. ) OR ( tap ((((trinh lam) OR (trinh luat))) OR (trinh lap)) minh duc. )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tiep can tam linh vuc. ) or ( tap ((((trinh lam) OR (trinh luat))) or (trinh lap)) minh duc. ))".
• Adding a wildcard symbol may retrieve word variants: (( tiep can tam linh vuc. ) or ( tap ((((trinh lam) OR (trinh luat))) or (trinh lap)) minh duc. ))*.
