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

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