Hi, I&#x27;m Evan an Engineer on Azure Search. I&#x27;m not aware of any published in depth comparison of the two services. We&#x27;d love to hear your thoughts and feedback if you&#x27;d like to give the service a try. We have a free tier that allows you to load up to 10k documents. If you do give it a try, please feel free to reach out to me at username at company.com.
