Thanks @fabe.
I resolved that issue after search init and change mysql config ( STRICT option ).
It works well but I found T6892.

Thank you for your answer. But I met this error message.
after "search index --all"

[HTTP/404] Not Found
{"error":"IndexMissingException[[phabricator] missing]","status":404}

Is it need more configuration for this?

Is there a temporary way to resolve this issue? ( Just only for wiki search )

Thanks @chad
I think gravatar option ( default = false ) is needed.

@chad
I think T6322 is different a little bit.
Change user picture was success, but it took very long time to see edit picture page.
Please check this,
