Description

Hi, our synapse homeserver is private and did not federate with matrix.org.

I wonder about that clients can't find local users from our homeserver.
So i took a look in database select * from user_directory_search;.
Surprisingly in this table there are a few users from matrix.org but no user from our own homeserver.
I don't know why this is the case, but i think it's strange. ?

The Homeserver configuration for user_directory is:

user_directory:
    enabled: true
    search_all_users: true
    prefer_local_users: true

Steps to reproduce

I have no clue how to reproduce this.

Anything else that would be useful to know?

Is there any way to rebuild the user_directory ?

I tried to run UPDATE user_directory_stream_pos SET stream_id = NULL;
Followed by a restart of synapse.
This didn't work for me.

So i Tried also:

curl --header "Authorization: Bearer TOKEN" -X POST 'http://10.1.1.20:8008/_synapse/admin/v1/background_updates/start_job' -d '{"job_name": "regenerate_directory"}'

But this also didn't work, user_directory remains the same.

I hope someone can clarify or help, i don't know if its a bug.
