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