Perhaps you should try some spelling variations:
"descriptive clause" » "descriptions clauses", "descriptive feature", "descriptive image"
"descriptive claims" » "descriptive ethics", "descriptive names"
"descriptions phase" » "descriptions plate", "descriptions places", "descriptions based"
"descriptive phase" » "descriptive plates", "descriptive image", "descriptive plan"
"description based" » "descriptor based", "description des"
"descriptive case" » "descriptive based", "description case", "descriptive name"

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