Perhaps you should try some spelling variations:
"descriptions papers" » "descriptions paper", "descriptions papetri", "description paper"
"descriptions phase" » "descriptions places", "descriptions based", "descriptions part"
"descriptions plate" » "descriptions places", "descriptions state", "descriptions template"
"descriptive phase" » "descriptive case", "descriptive plates", "descriptive clause"

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 ("descriptions papers")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"descriptive phase\") OR (\"descriptions phase\"))) or (((\"descriptions plate\") or (\"descriptions papers\"))))".
• Removing quotes may allow a broader search: (((( descriptive phase ) OR ( descriptions phase ))) or ((( descriptions plate ) or ( descriptions papers )))).
• Adding a wildcard symbol may retrieve word variants: (((("descriptive phase") OR ("descriptions phase"))) or ((("descriptions plate") or ("descriptions papers"))))*.
