Trying to search Sharepoint files using Microsoft Graph api

Question

We are using the Microsoft Graph API (new, Office365 unified API renamed to this recently). We have an OAUTH login, with the graph.microsoft.com resource used to generate a token. It works fine to get other subresources such as /me. But when using the URL in Microsoft Graph's documentation that talks about searching drive (and SharePoint?) we cannot find a way to make any sample URL work. It doesn't work when a drive is available for the user nor when SharePoint.

So first question, why does this generate an error?

GET https://graph.microsoft.com/v1.0/drive/root/Microsoft.Graph.search?q=img

Rreturns a bad request:

Error: 400 - Bad Request
See Response Headers for details.
{
"error": {
"code": "BadRequest",
"message": "Unsupported segment type.",
"innerError": {
  "request-id": "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX",
  "date": "2015-11-23T16:58:26"
}
}
}

Here is the Response Header:

request-id: XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX
client-request-id: XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXX

And second part of the question, does this also search Sharepoint as it hints? There is no separate API for doing so within the graph API.

Answer 1

The correct request URL is https://graph.microsoft.com/v1.0/drive/root/microsoft.graph.search(q='img')

I created https://github.com/OfficeDev/microsoft-graph-docs/issues/51 to correct the documentation.
