"Open Source Search tool provided by AWS"
4/5

AWS has developed this open search tool which brings a lot of convenience and ease of use. It can help users optimize their applications and extract valuable insights from data. This tool helps maintain the core functionality of Elasticsearch. It also helps provision servers, configure networks, and storage. It also helps deploy the cluster in just a few clicks. AWS support is also available 24/7 for this. Review collected by and hosted on G2.com.

There is some dislike of this tool, such as you can use a maximum of 40 data per node per cluster. Also, using AWS Open Search Service, you are locking yourself into the AWS ecosystem in a long-term contract. Review collected by and hosted on G2.com.

"Smoothen the data-manipulation and visualization tasks"
3.5/5
What do you like best about OpenSearch?

OpenSearch's easy integration with AWS is a real breakthrough. It seems like problems as simple as setting up clusters and visualization become easy and fast, taking away countless hours of work and frustration. Learned to develop multiple dashboards, so it was easier to detect the problems and debug the routine activities, resulting in more work done and improved efficiency. And the energy in addition to the consummate power and flexibility of the search engine make it a great tool, executing even the most complicated questions with all ease. Review collected by and hosted on G2.com.

What do you dislike about OpenSearch?

Opposed to the other open-source solutions, it blows the budget for the small teams of amateurs or hobbyists. Moreover, I also have to wait for new versions to mature and, sometime, it becomes a pain, especially when I am under a tight deadline like never. My usage of the recommendations depends on the limitations for searchable fields, whereas there are ways to overcame the issues, more searchable field would be a benefit.
