Perhaps you should try some spelling variations:
"descriptions places" » "descriptions plate", "descriptions plus", "descriptions paper"
"descriptions based" » "description based", "descriptors based", "descriptions a"
"descriptive phase" » "descriptive plates", "descriptions phase", "descriptive clause"
"descriptive case" » "descriptive clause", "descriptive based", "description case"

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 ((("descriptions places") OR ((("descriptions based") OR ("descriptor based")))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"descriptive phase\") or (\"descriptive case\"))) or (((\"descriptions places\") or (((\"descriptions based\") OR (\"descriptor based\"))))))".
• Removing quotes may allow a broader search: (((( descriptive phase ) or ( descriptive case ))) or ((( descriptions places ) or ((( descriptions based ) OR ( descriptor based )))))).
• Adding a wildcard symbol may retrieve word variants: (((("descriptive phase") or ("descriptive case"))) or ((("descriptions places") or ((("descriptions based") OR ("descriptor based"))))))*.
