Perhaps you should try some spelling variations:
"descriptive plates" » "descriptive poem", "descriptive data"
"descriptions phase" » "descriptions plate", "descriptions places", "descriptions based"
"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 ("descriptive plates"))) OR ("descriptions phase")).
• Removing quotes may allow a broader search: (((( descriptive case ) or ( descriptive plates ))) or ( descriptions phase )).
• Adding a wildcard symbol may retrieve word variants: (((("descriptive case") or ("descriptive plates"))) or ("descriptions phase"))*.
