Perhaps you should try some spelling variations:
descriptions phase » descriptions plate, descriptions places, descriptions based
descriptions paper » descriptions papers, description paper, descriptions papetri
descriptive case » descriptive clause, descriptive based, descriptive phase

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: "((\"descriptive case\") or (\"((descriptions phase) OR (descriptions paper))\"))".
• Removing quotes may allow a broader search: (( descriptive case ) or ( ((descriptions phase) or (descriptions paper)) )).
