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