Perhaps you should try some spelling variations:
la literatura » la litterature, a literature
table studie » table studies, cable studies, table study
a literatura » a literature, y literatura, a literatur
tests table » test tables, results table, test suitable
e filosofia » la filosofia
studie e » studie 2, studie _, studie 1

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 table studie e filosofia ((a literatura) OR (la literatura))*".
