Search multiple files in subdirectories for each string in a list and return a list of strings found

I have a folder with ~20,000 files in multiple subfolders. The files have varying extensions, but their content is all text. I also have a text list of ~500 names. I'd like to search all the files for each name in the text list, one at a time, for the purpose of determining if that name appears in any of the files.

The desired output is a text list of ~500 lines (or however many names were searched), each with a 1 (if the name was found, regardless of how many times) or a 0 (if not). The order of this file would match the input text list.

e.g., 

searchstring.txt
   nameA
   nameB
   nameC

searchfolder
  subfolder1
      file.abc    (references name A)
      file2.xyz   (no references)
  subfolder2
      file.xyz     (no references)
      file3.xyz    (references name A)
  subfolder3
      file4.abc     (no references)
      file5.xyz    (references name A, name C)

result.txt
   1
   0
   1

Ideally the search would be called be with a batch file with commands available on Windows 7 and up. The environment may not have Admin permissions.
