Perhaps you should try some spelling variations:
deep filosofica » de filosofia, e filosofica
scale studies » scale study
la literatura » la litterature
studies deep » studied deep, studies dewey, studies der
tests scale » tests stable, sets scale, tests safe

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "tests scale studies deep filosofica ((la literatura) OR (a literature))*".
