I'm using a metadata search in box api:
https://api.box.com/2.0/search?mdfilters=
The search is ok, but I'm passing metadata for search, but after return I receive only file information, not any metadata from files. Is it possible search by metadata in box api and return file and metadata together?
This does not appear possible. Your best option is to request all file metadata using the file ID returned in the search result. If you get multiple search results consider sending the metadata requests in parallel (up to ~10 requests/user/sec) to speed things up.
