Perhaps you should try some spelling variations:
"descriptive clause" » "descriptive claims", "descriptions clauses", "descriptive feature"
"descriptions plate" » "descriptions places", "descriptions phase", "descriptions template"
"descriptions state" » "descriptions system", "descriptions some", "descriptions soil"
"descriptive phase" » "descriptive plates", "descriptions phase", "descriptive image"
"descriptive case" » "descriptive based", "description case", "descriptive name"

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