Perhaps you should try some spelling variations:
una pala » una parola, una paria, una scala
una cala » una scala, una casa, una carta
y und » _ und, 1 und, i und
2 und » _ und, 1 und
y un » y una, _ un, a un

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: con ((una pala) OR (una cala)) ((y un) OR (((y und) OR (2 und)))) sombrero.
• The words AND, OR and NOT may confuse the search; try adding quotes: "con ((una pala) OR (una cala)) ((y un) or (((y und) or (2 und)))) sombrero".
• Adding a wildcard symbol may retrieve word variants: con ((una pala) OR (una cala)) ((y un) or (((y und) or (2 und)))) sombrero*.
