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