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