Perhaps you should try some spelling variations:
et litterature » la litterature, art literature
studies does » studies dress, studies ds, studies der
filosofia et » filosofia e, filosofia en, filosofia del
studies die » studie die, studien die, studies dose
text case » text class, text csv, context case
text code » text copy, text co

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 case) OR (text code)) ((studies die) OR (studies does)) filosofia et litterature.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((text case) or (text code)) ((studies die) OR (studies does)) filosofia et litterature".
• Adding a wildcard symbol may retrieve word variants: ((text case) or (text code)) ((studies die) OR (studies does)) filosofia et litterature*.
