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