Perhaps you should try some spelling variations:
et litterature » la litterature
de litterature » la litterature
art literature » market literature
e filosofia » la filosofia
text code » text copy, text co
text case » text class, text csv, context case

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: ((text code) OR (text case)) studies e filosofia ((de litterature) OR (((et litterature) OR (art literature))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((text code) OR (text case)) studies e filosofia ((de litterature) or (((et litterature) or (art literature))))*".
