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