• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ty) or (sach thu)) nang xa hoi. lieu va tham xuc va hanh ((di cua) OR (de cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach thu)) nang xa hoi. lieu va tham xuc va hanh ((di cua) OR (de cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) or (sach thu)) nang xa hoi. lieu va tham xuc va hanh ((di cua) OR (de cua)) tre".
• Adding a wildcard symbol may retrieve word variants: te ((sach ty) or (sach thu)) nang xa hoi. lieu va tham xuc va hanh ((di cua) OR (de cua)) tre*.
