Perhaps you should try some spelling variations:
"descriptive clause" » "descriptive case", "descriptions clauses", "descriptive feature"
"descriptive claims" » "descriptive ethics", "descriptive names"
"descriptions based" » "description based", "descriptors based", "descriptor based"
"descriptive phase" » "descriptive case", "descriptive plates", "descriptions phase"
"descriptions part" » "description part", "descriptors part", "descriptions a"

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 claims"))))) OR ((("descriptions part") OR ("descriptions based")))).
• Removing quotes may allow a broader search: (((( descriptive phase ) or ((( descriptive clause ) or ( descriptive claims ))))) or ((( descriptions part ) or ( descriptions based )))).
• Adding a wildcard symbol may retrieve word variants: (((("descriptive phase") or ((("descriptive clause") or ("descriptive claims"))))) or ((("descriptions part") or ("descriptions based"))))*.
