Perhaps you should try some spelling variations:
des filosofica » de filosofia, e filosofica, e filosofia
results table » results tables, results time, results three
de literatura » de litterature, y literatura, a literatura
la literatura » la litterature, a literature
tests table » test tables, test suitable, lists tables
studien des » studien der, studie des, studien aus

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