Unable to search file in Dropbox for business' account using Dropbox Api

[Shiza]

Hi, I'm trying to search a file in a dropbox buisness account. I am able to use the search api for an individual dropbox but i want to be able to acheive the same thing for a buisness account aswell. I can list the folders using the api aswell and create a folder in dropbox buisness account but not search.

I used this to make the api call --> https://api.dropboxapi.com/2/files/search_v2

in the header i passed these four parameters

* Authorization: Bearer sl.........
* Content-Type: application/json
* Dropbox-API-path_Root: {".tag": "root", "root": "name-space-id"}
* Dropbox-API-Select-User: dbmid:.....

In body I'm passing 

{

    "query": "23-017) 12 Greenwich Road SE7.lnk"

}

Its gives a response of 200 on postman but it should have returned the path and details of that file.

its gives this response

{

    "has_more": false,

    "matches": []

}

I dont know what I'm doing wrong
