Perhaps you should try some spelling variations:
descriptive phase » descriptive plates, descriptions phase, descriptive clause
descriptions plus » descriptions part, descriptions all, descriptions des
descriptive case » descriptive clause, descriptive based, description case

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