• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sac ky) OR (sai ky)) tang lai roi. hieu vu chao xu va hanh ((vi cua) OR (vai cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sac ky) OR (sai ky)) tang lai roi. hieu vu chao xu va hanh ((vi cua) or (vai cua)) te".
• Adding a wildcard symbol may retrieve word variants: tu ((sac ky) OR (sai ky)) tang lai roi. hieu vu chao xu va hanh ((vi cua) or (vai cua)) te*.
