Perhaps you should try some spelling variations:
"descriptive plates" » "descriptive poem"
"descriptions phase" » "descriptions plate", "descriptions places", "descriptions part"
"descriptions based" » "description based", "descriptors based", "descriptor based"
"descriptive data" » "descriptive _"

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 plates") OR ("descriptive data"))) OR ((("descriptions phase") OR ("descriptions based")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"descriptive plates\") OR (\"descriptive data\"))) or (((\"descriptions phase\") or (\"descriptions based\"))))".
• Removing quotes may allow a broader search: (((( descriptive plates ) OR ( descriptive data ))) or ((( descriptions phase ) or ( descriptions based )))).
• Adding a wildcard symbol may retrieve word variants: (((("descriptive plates") OR ("descriptive data"))) or ((("descriptions phase") or ("descriptions based"))))*.
