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