• Performing a fuzzy search may retrieve terms with similar spellings: theo lieu tinh - hanh ((((thang cua) OR (than cua))) or (tranh cua)) nhung cong tuan van ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo lieu tinh - hanh ((((thang cua) OR (than cua))) OR (tranh cua)) nhung cong tuan van ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo lieu tinh - hanh ((((thang cua) OR (than cua))) or (tranh cua)) nhung cong tuan van ban*".
