• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ly va cay phoi. hieu va ((cac xuc) OR (chat xuc)) va hanh ((de cua) OR (dieu cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ly va cay phoi. hieu va ((cac xuc) OR (chat xuc)) va hanh ((de cua) or (dieu cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: tu san ly va cay phoi. hieu va ((cac xuc) OR (chat xuc)) va hanh ((de cua) or (dieu cua)) tre*.
