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