Perhaps you should try some spelling variations:
table studies » cable studies, bible studies, male studies
eagle studies » angle studies, cable studies, exile studies
filosofica a » filosofica da, filosofica _, filosofico a
filosofica e » filosofia e, filosofica da, filosofia de

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: tests ((table studies) OR (eagle studies)) de ((filosofica a) OR (filosofica e)) literatura.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tests ((table studies) OR (eagle studies)) de ((filosofica a) or (filosofica e)) literatura".
• Adding a wildcard symbol may retrieve word variants: tests ((table studies) OR (eagle studies)) de ((filosofica a) or (filosofica e)) literatura*.
