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.

Automated indexing has streamlined document search workflows but semantic relevance and setup complexity still need improvement
We used the semantic search capabilities of Azure AI Search, but we haven't gotten good results in the semantic search. So we are exploring with ChromaDB, and Cosmos is having the capability of doing the semantic search as well. We are exploring that. A few queries we use analytics search, which works and is good. Analytics search is good. We are trying the ML capabilities of the product since we are using Databricks and other tools for building the models, MLflow, and related items. We are still working on proof of concepts, which could be better with ChromaDB or Cosmos or vector search or inbuilt Databricks vector stores. Language processing is not about user intention; it's about the context. If there is a document and you want to know the context of a particular section, then we would use vector search. Instead of traversing through the whole document, while chunking it into the vector, we'll categorize and chunk, and then we'll look only at those chunks to do a semantic search. When comparing Azure AI Search, I'm doing a proof of concept because with ChromaDB I can create instances using LangChain anywhere. For per session, I can create one ChromaDB and can remove it, which is really useful for proof of concepts. Instead of creating an Azure AI Search instance and doing that there, that is one advantage I'm seeing for the proof of concept alone, not for the entire product. I hope it should support all the embedding providers as well. Is there a viewer or tool similar to Storage Explorer? We are basically SQL-centric people, so we used to find Cosmos DB very quick for us when we search something and create indexes. I guess there is some limitation in Azure AI Search. I couldn't remember now, such as querying limitations. I'm not remembering that part.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I've found the solution to be very scalable."
"The best feature is its scalability in that Cloud is always on the fly."
"Storage of photos and files which can be accessed anyplace, anytime, extremely quickly."
"It will remain alive in the market. The solution will be stable in the market."
"There are plenty of services from the database, with many valuable features, good scalability and agility, okay pricing, good solution quality, strong optimization, and customization that can work with any other cloud platforms."
"AWS CloudSearch's best features are good performance under high CPU and memory use, and ease of deployment and scaling."
"It is remarkably efficient and beneficial."
"CDN service reduces latency when accessing our web application."
"The features in Azure AI Search that are most valuable include the ability to automate index creation, and you can drop in the blob storage or drop in the SQL table, which will get automatically indexed."
"It provides good access capabilities to various platforms."
"The product is pretty resilient."
"The customer engagement was good."
"The product is extremely configurable, allowing you to customize the search experience to suit your needs."
"The solution's initial setup is straightforward."
"Because all communication is done via the REST API, data is retrieved quickly in JSON format to reduce overhead and latency.​"
"The broad access capability is probably the most valuable feature, as it provides access with hardly any physical infrastructure."
 

Cons

"Regarding the period of propagation on CDN servers, sometimes we update photos or files and we don't see the update instantly. We need to wait for sometime, which is quite boring because we may be setting up a marketing campaign which is related to the product's photo and we need to wait to start."
"Amazon AWS CloudSearch is highly stable. However, the speed depends on your internet connection."
"The price of the solution can be expensive."
"AWS CloudSearch's documentation isn't very clear. Also, the on-premise version of the solution is less stable than the cloud version."
"The biggest improvement area is that Amazon AWS CloudSearch feels a little older compared to newer AWS services."
"We'd like to see more database features."
"A reboot should be enhanced."
"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."
"For availability, expanding its use to all Azure datacenters would be helpful in increasing awareness and usage of the product.​"
"It would be good if the site found a better way to filter things based on subscription."
"The after-hour services are slow."
"On a scale from one to ten where one is the worst and ten is the best, I would rate Azure Search as probably a six-out-of-ten."
"The pricing is room for improvement."
"The initial setup is not as easy as it should be."
"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."
"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."
 

Pricing and Cost Advice

"Amazon AWS CloudSearch charging is based on how many resources you consume or and the solution is known to be a bit expensive."
"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."
"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."
"Our license costs around $4,000 per month."
"There was no license needed to use this solution."
"In comparison to IBM and Microsoft, the pricing is more favorable."
"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."
"I would rate the pricing an eight out of ten, where one is the low price, and ten is the high price."
"The solution is affordable."
"For the actual costs, I encourage users to view the pricing page on the Azure site for details.​"
"The cost is comparable."
