Hello again, I was able to resolve this on my own. For those experiencing similar issues, I had 2 errors. First I was not reading my input as UTF-8, which evidently is necessary (I knew the results were returned in UTF-8, but apparently I have to submit it as well in this encoding). Second, I had the language flag set to english (the default setting which was provided in the example scripts for optimizations) which seemed logical, but when I disabled it, all the results I sent came through. Even though the keywords were english, disabling the language made the difference.
