Perhaps you should try some spelling variations:
"descriptions phase" » "descriptions plate", "descriptions places", "descriptions part"
"descriptive clause" » "descriptive claims", "descriptions clauses", "descriptive feature"
"descriptions based" » "description based", "descriptors based", "descriptor based"
"descriptive phase" » "descriptive plates", "descriptive image", "descriptive plan"
"descriptive case" » "descriptive based", "descriptive name", "descriptive image"
"description case" » "description causes", "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 clause") OR ((((("descriptive case") OR ("description case"))) OR ("descriptive phase"))))) OR ((("descriptions phase") OR ("descriptions based")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"descriptive clause\") or (((((\"descriptive case\") OR (\"description case\"))) or (\"descriptive phase\"))))) or (((\"descriptions phase\") or (\"descriptions based\"))))".
• Removing quotes may allow a broader search: (((( descriptive clause ) or ((((( descriptive case ) OR ( description case ))) or ( descriptive phase ))))) or ((( descriptions phase ) or ( descriptions based )))).
• Adding a wildcard symbol may retrieve word variants: (((("descriptive clause") or ((((("descriptive case") OR ("description case"))) or ("descriptive phase"))))) or ((("descriptions phase") or ("descriptions based"))))*.
