Perhaps you should try some spelling variations:
y literatura » la literatura
filosofia y » filosofia e, filosofia _, filosofia de
bast scale » best scale, vast scale, basin scale
studien di » studien die, studien der, studien bei
studien dd » studies dd, studien der, studien die

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: "bast scale ((studien di) OR (studien dd)) filosofia y literatura".
• Adding a wildcard symbol may retrieve word variants: bast scale ((studien di) OR (studien dd)) filosofia y literatura*.
