Is it possible to implement Swiftype search such that it will work in browsers that have JavaScript switched off?
Yes, you can use Swiftype without JavaScript. However, you’ll need to manually implement submission of queries to your server, submit them from your server to our API, and then render the results.
There is an example of doing this in our Rails example application. See the “Search with server pass-through” section of the Rails tutorial.
There’s also no reason you can’t do both. Users with JavaScript enabled will have a faster search experience, but users without JavaScript will still be able to perform searches.
