• Performing a fuzzy search may retrieve terms with similar spellings: toc sach ly hang xa hoi. ((lieu va) or (thi van)) ((cam luc) OR (cau luc)) va dinh vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach ly hang xa hoi. ((lieu va) OR (thi van)) ((cam luc) OR (cau luc)) va dinh vi cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ly hang xa hoi. ((lieu va) or (thi van)) ((cam luc) OR (cau luc)) va dinh vi cuu tre".
• Adding a wildcard symbol may retrieve word variants: toc sach ly hang xa hoi. ((lieu va) or (thi van)) ((cam luc) OR (cau luc)) va dinh vi cuu tre*.
