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