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