• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ty) OR (sach thu)) xang xa hoi. thien van luat ((duoc va) or (duc va)) hang tai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach thu)) xang xa hoi. thien van luat ((duoc va) OR (duc va)) hang tai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) OR (sach thu)) xang xa hoi. thien van luat ((duoc va) or (duc va)) hang tai cua tre".
• Adding a wildcard symbol may retrieve word variants: te ((sach ty) OR (sach thu)) xang xa hoi. thien van luat ((duoc va) or (duc va)) hang tai cua tre*.
