der filosofia » de filosofia, e filosofia, da filosofia
la literatura » la litterature, a literature
di filosofia » la filosofia, e filosofia
sets state » nets state, sets shape, sets style
sets late » sets rate, sets large, sets label

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: ((sets late) OR (sets state)) studenten ((der filosofia) OR (di filosofia)) la literatura.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((sets late) or (sets state)) studenten ((der filosofia) OR (di filosofia)) la literatura".
• Adding a wildcard symbol may retrieve word variants: ((sets late) or (sets state)) studenten ((der filosofia) OR (di filosofia)) la literatura*.
