• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach hoa toc thieu nhi cua ets : ((((nhung bo) OR (nhung don))) OR (nhung bi)) oc vi đai.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach hoa toc thieu nhi cua ets : ((((nhung bo) OR (nhung don))) or (nhung bi)) oc vi đai".
• Adding a wildcard symbol may retrieve word variants: tu sach hoa toc thieu nhi cua ets : ((((nhung bo) OR (nhung don))) or (nhung bi)) oc vi đai*.
