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