One frustrating shortcoming of accessing SMB shares from macOS is the default failure of directory indexing for file searching. You simply can’t use the normal Finder “Search” field to do anything. This makes it particularly tedious to interact with large SMB shares when you don’t know exactly where the files you want are located.
The solution at the link is simple, if obscure: select the
fruit object from the available VFS Objects under the Advanced configuration of the share in question. Thanks to Spiceworks user David_CSG for dropping a hint about vfs_fruit that led me to this solution.
