CustomField type Textarey, select the option Search: add as Taxonomy or Makes searchable and add as Taxonomy. Create posts with more than 256 characters of content in the CustomField. Perform Smart Search Index. In my case, there was already the CustomField Textarea and many posts with content in the CustomField.
