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

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 case") OR ((("descriptions places") OR ("descriptions based")))).
• Removing quotes may allow a broader search: (( descriptive case ) or ((( descriptions places ) or ( descriptions based )))).
• Adding a wildcard symbol may retrieve word variants: (("descriptive case") or ((("descriptions places") or ("descriptions based"))))*.
