Perhaps you should try some spelling variations:
"descriptions state" » "descriptions system", "descriptions soil", "descriptions illustrated"
"descriptive phase" » "descriptive case", "descriptive plates", "descriptions phase"
"descriptions some" » "description some", "descriptions soil", "descriptions system"

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