Search workflows have become faster and our team manages operational records more efficiently
Improvements for Amazon AWS CloudSearch can be made, but I will first start with the biggest improvement. The biggest improvement area is that Amazon AWS CloudSearch feels a little older compared to newer AWS services. The second thing about improvement is the documentation. The documentation could definitely be refreshed with more practical examples and troubleshooting scenarios. During setup, a few indexing issues took longer to diagnose because error messages were pretty generic. Better debugging visibility would reduce trial-and-error work. Monitoring is decent through Amazon CloudWatch, but I would like more detailed search-level diagnostics out of the box. Sometimes it is not obvious why certain queries rank results differently unless you manually test a lot. More transparent query analysis, indexing, and insights would be useful. Logging exists, but deeper visibility would help during optimization.

Rag workflows have improved document search and reduced development effort for client projects
In my experience, the best features Azure AI Search offers are that it is very easy to upload documents and they can obviously be very agile and we can query upon these documents very easily. When I say it is easy to upload and query documents, it makes the application more reliable in the case that if we have a certain study or certain use case wherein just that PDF or just those amount of information will be used and not the entire thing, so the user can just go quickly and search for that documentation. I think it is fully integrated with Azure and we use Azure primarily for our primary cloud platform, so that helps very much in integrating and in maintaining one service provider. Regarding Azure AI Search's AI capabilities, it provides good security in terms of reliability and scalability as well, so there are no concerns for it regarding those issues. Regarding Azure AI Search's AI capabilities, it is accurate and reliable 99% of the time.

Cons

"The biggest improvement area is that Amazon AWS CloudSearch feels a little older compared to newer AWS services."
"The solution should improve the recovery aspects that it has on offer."
"AWS CloudSearch's documentation isn't very clear. Also, the on-premise version of the solution is less stable than the cloud version."
"Amazon AWS CloudSearch is highly stable. However, the speed depends on your internet connection."
"In terms of what needs improvement, I would say that it needs to keep its cost competitive in the market, especially in comparison to other clouds."
"A reboot should be enhanced."
"We'd like to see more database features."
"Index cleanup is sometimes painful. No easy way to clean indexes or a bulk of documents. Full indexing or regeneration of entire indexes sometimes gets stuck. In one instance, we had to delete the entire index and re-create it."
"The after-hour services are slow."
"Adding items to Azure Search using its .NET APIs sometimes throws exceptions."
"It would be good if the site found a better way to filter things based on subscription."
"They should add an API for third-party vendors, like a security operating center or reporting system, that would be a big improvement."
"The pricing is room for improvement."
"For SDKs, Azure Search currently offers solutions for .NET and Python. Additional platforms would be welcomed, especially native iOS and Android solutions for mobile development."
"I think Azure AI Search can be improved by implementing it with the agents as well, and I think that their agent integration is something they could work upon or they can improve it very easily or without managing anything, but apart from that, it is building basic functionalities of RAG, but if that would be expanded to agents as well, then that would be very useful."
"Azure AI Search could be improved primarily because the UX and UI could be a little bit more intuitive for persons since the learning curve could be a little bit high."
 

Pricing and Cost Advice

"There was no license needed to use this solution."
"Amazon AWS CloudSearch charging is based on how many resources you consume or and the solution is known to be a bit expensive."
"In comparison to IBM and Microsoft, the pricing is more favorable."
"Our license costs around $4,000 per month."
"I'm not sure how much we pay a year. It might be around $30,000 a year."
"We chose AWS because of its cost and stability."
"On a scale of one to ten, where one point is cheap, and ten points are expensive, I rate the pricing as medium or reasonable."
"For the actual costs, I encourage users to view the pricing page on the Azure site for details.​"
"I would rate the pricing an eight out of ten, where one is the low price, and ten is the high price."
"The cost is comparable."
"The solution is affordable."
"I think the solution's pricing is ok compared to other cloud devices."
"​When telling people about the product, I always encourage them to set up a new service using the free pricing tier. This allows them to learn about the product and its capabilities in a risk-free environment. Depending on their needs, the free tier may be suitable for their projects, however enterprise applications will most likely required a higher, paid tier."
