Finds emails whose body contains some text. Unlike email search, this searches the body itself:

{ "body": { "fuzzy_contains": "proposal" } }

Matching is fuzzy, so similar spellings also match. By default bodies are searched as English. To search other languages, list them in the Accept-Language header; en, fr, de, es and nl are supported.

The response is an array of up to 25 email references, best matches first. It is not paged. Emails in the trash are skipped, and only emails the user is allowed to see are included.
