Perhaps you should try some spelling variations:
before school » reform school, before preschool
school versus » schools versus, school census
a transformed » _ transformed, _ transformer, a transforming
transformed 1 » transformed _, transformer 1, transformed a
values why » value why, values what, values when
langue de » langue du, lange der
vague de » vagues de, vue de, vague _
a before » 1 before, 3 before, c before
why a » why _
1 cao » 1 can, 1 ao, _ cao

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((vague de) OR (langue de)) a before school versus ) OR ( values why a transformed 1 cao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((vague de) OR (langue de)) a before school versus ) or ( values why a transformed 1 cao ))~".
• Adding a wildcard symbol may retrieve word variants: (( ((vague de) OR (langue de)) a before school versus ) or ( values why a transformed 1 cao ))*.
