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 case", "descriptive plates", "descriptive clause"

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