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