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