Perhaps you should try some spelling variations:
feature scale » feature space, feature shape, feature scaling
de literatura » de litterature, la literatura, y literatura
filosofia de » filosofia del
study lca » study lia, study loa, study local
study la » study law, study lay, study lia

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: "feature scale ((study la) OR (study lca)) filosofia de literatura".
• Adding a wildcard symbol may retrieve word variants: feature scale ((study la) OR (study lca)) filosofia de literatura*.
