Re: Dropbox search may not be working as expected

The Dropbox API search functionality doesn't have a parameter to control that behavior, nor documentation or a guarantee on the specific expected behavior for that. However in my testing it does currently seem to behave as you want, that is, when specifying multiple tags in the "query", it is returning only files that contain both tags for me.

Here's an example of what I'm seeing:

curl -X POST https://api.dropboxapi.com/2/files/search_v2 \
  --header 'Authorization: Bearer <ACCESS_TOKEN>' \
  --header 'Content-Type: application/json' \
  --data '{"query":"#banana","options":{"path":"/files with tags"}}'

#   "matches": [
#     {
#       "match_type": {
#         ".tag": "file_content"
#       },

For context: there are three files, one with one tag, one with a different tag, and one with both tags.

If you're seeing otherwise, can you share a sample so I can check on that with the team for you? Please show the search parameters you're using, as well as the full result you're getting back, but be sure to redact the access token itself. Feel free to open an API ticket if you'd prefer to share privately. Thanks!
