title: Does SharePoint API offer an endpoint for doing a full text search on the content of the documents?
body: <p>I am using SharePoint as a DMS for my app.
  Via the SharePoint API I am uploading, and downloading files, and retrieving folders and files.
  I have been using the standard url blueprint:
  <code>https://{{TenantName}}.sharepoint.com/sites/{{SiteName}}/_api/web/...</code></p>
  <p>I need to add a full text search in the app. I need to be able to send a queryString parameter to the API, and to get returned all files that contain that string. Not in their name, but in their content.</p>
  <p>Is that even possible? Could not find it online. Any help is greatly appreciated.</p>
