So far, I haven't found any limitations. It might be less scalable than Elasticsearch, but I haven't tested its limits yet.

Azure Search is entirely sufficient for the amount of information we index. Overall, I would rate the scalability an eight out of ten. The end-user community is around 50,000. Azure Secure is used on a daily basis in our company.

I would rate Azure Search an eight to nine out of ten regarding scalability. The scalability of Azure Search is very good. As a platform, Microsoft Azure is very good. We have never seen scalability issues. We have many users using this solution at the moment.

I rate the solution's scalability a seven out of ten. We have approximately 800 users in our organization.

The tool is scalable.

We have not had the need to explore the capabilities for scaling the use of the product. It is meeting our needs currently. There are not any scalability limitations that I am aware of.  

Azure Search offers five levels of service, depending on the amount of data being stored and indexed. These options allow for a variety of solutions from small, free search solutions, to large, enterprise level integrations. Because the product is hosted in Microsoft Azure, scalability has never been a concern.
