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