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

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 phase) OR (descriptive clause))\") or (\"((descriptions phase) OR (descriptions based))\"))".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"((descriptive phase) OR (descriptive clause))\\") or (\\"((descriptions phase) or (descriptions based))\\"))\"".
• Removing quotes may allow a broader search: (( ((descriptive phase) OR (descriptive clause)) ) or ( ((descriptions phase) or (descriptions based)) )).
