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

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