// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Use your previously obtained access token here:
// See the following examples for getting an access token:
//    Get Microsoft Graph OAuth2 Access Token (Azure AD v2.0 Endpoint).
//    Get Microsoft Graph OAuth2 Access Token (Azure AD Endpoint).
//    Refresh Access Token (Azure AD v2.0 Endpoint).
//    Refresh Access Token (Azure AD Endpoint).

// (Make sure your token was obtained with the FilesRead or Files.ReadWrite scope.)

// Sends the following GET request:

// Search the entire drive like this:
// If not using "me", then the path should be /v1.0/users/{id | userPrincipalName}/...
// GET /v1.0/me/drive/root/search(q='{search-text}')

// Or search under a particular folder like this:
// GET /v1.0/me/drive/root:/{item-path}:/search(q='{search-text}')

// This example will search for files in or under the "/Misc" directory, having "penguin" in the file path.
