• Performing a fuzzy search may retrieve terms with similar spellings: su dai ly hang xa hoi. ((hieu va) or (lieu va)) cac ((toc va) OR (toc ta)) thanh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su dai ly hang xa hoi. ((hieu va) OR (lieu va)) cac ((toc va) OR (toc ta)) thanh vi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su dai ly hang xa hoi. ((hieu va) or (lieu va)) cac ((toc va) OR (toc ta)) thanh vi cua tre*".
