I am using Swiftype site search. I am wondering if it's possible to download the indexing file?

We are using the Swiftype site search for our online documentation built with Sphinx. Some of our customers doesn’t have internet enable in the machine that installed our application, so we also include a copy of the documentation along with their application installation. Once a version of the application is released, the documentation for that version won’t have many updates. I am wondering if we can download the site search indexing files and use it locally for the locally static HTML documentation?
