Perhaps you should try some spelling variations:
descriptions phase » descriptions plate, descriptions places, descriptions part
descriptions based » description based, descriptors based, descriptor based
descriptive case » descriptive clause, descriptive based, descriptive phase

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