Perhaps you should try some spelling variations:
da literatura » a literatura, de literatura, na literatura
la literatura » la litterature, a literature
a filosofica » a filosofia, e filosofica, la filosofia
burst scale » bast scale, best scale, just scale
set scale » sets scale, belt scale, best scale

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: ((set scale) OR (burst scale)) studies a filosofica ((da literatura) OR (la literatura)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((set scale) or (burst scale)) studies a filosofica ((da literatura) OR (la literatura))".
• Adding a wildcard symbol may retrieve word variants: ((set scale) or (burst scale)) studies a filosofica ((da literatura) OR (la literatura))*.
