I tested the Parse.com documentation (https://www.parse.com/docs/search#stq=xcode) and found some problems with swiftype.

When searching via Chrome, I kept getting a blank content area with no search results. I did some digging (thinking that the issue might be that I reject 3rd party cookies) and I found the problem:

https://swiftype.com/embed.js wasn't loading. I went to view this script in my browser and got an error which was preventing the script from executing: "The identity of this website has not been verified. Server's certificate is not trusted." I clicked "proceed" to view the script in the browser, and when I went back to the search page, it worked as intended.
