• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((vu nang) or (van nang)) x hoi. hieu van chat ((xuc va) OR (tuc va)) dan bat cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((vu nang) OR (van nang)) x hoi. hieu van chat ((xuc va) OR (tuc va)) dan bat cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((vu nang) or (van nang)) x hoi. hieu van chat ((xuc va) OR (tuc va)) dan bat cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((vu nang) or (van nang)) x hoi. hieu van chat ((xuc va) OR (tuc va)) dan bat cua tre*.
