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

Try widening your search to All Fields.

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 ((((("descriptions phase") OR ("descriptions plate"))) OR ("description based")))).
• Removing quotes may allow a broader search: (( descriptive plates ) or ((((( descriptions phase ) or ( descriptions plate ))) or ( description based )))).
• Adding a wildcard symbol may retrieve word variants: (("descriptive plates") or ((((("descriptions phase") or ("descriptions plate"))) or ("description based"))))*.
