The Webform Submission Search API module provides search_api processors to index fields on Webform Submissions.
Included are examples for the Title, Description, text, Flagging, and Taxonomy reference fields.
Once indexed, the fields can be used elsewhere, e.g. in Views.

- Webform
Add the fields you want to index to the Search API index.
After indexing is performed you can add this field into a view.
