A working search index under Windows would be a unique selling point of Boxcryptor compared to Cryptomator.
Boxcryptor uses the commercial product CBFS Connect as the basis for its virtual file system under Windows - but unfortunately probably not in a current version. Because already since version 20.0.7649 this software has been adapted with the function SupportSearchIndexer to changes that Microsoft has made to Windows:

Thus, the problem in CBFS Connect has already been fixed. When will Boxcryptor update this component?
