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

"In our case, AWS is the best in the market, actually."
"It's the best solution for any company. It has a hosting ERP system for any task. AWS is stable. AWS is more flexible and its elastic concept is a new concept. AWS is also very secure. It has many layers of security, like hardware security and software security. This is a big issue."
"The best feature is its scalability in that Cloud is always on the fly."
"It is remarkably efficient and beneficial."
"Storage of photos and files which can be accessed anyplace, anytime, extremely quickly."
"We were able to build the core search functionality using this product."
"Document indexing, text-based search API, and Geospatial searches are all good features."
"I've found the solution to be very scalable."
"Azure Search is well-documented, making it easy to understand and implement."
"The solution's initial setup is straightforward."
"Azure Search provides plenty of benefits for business teams and sales teams, as it's a CLM system that helps you find everything related to specific customers and deals."
"The broad access capability is probably the most valuable feature, as it provides access with hardly any physical infrastructure."
"Because all communication is done via the REST API, data is retrieved quickly in JSON format to reduce overhead and latency.​"
"The product is extremely configurable, allowing you to customize the search experience to suit your needs."
"By implementing Azure Search, I have been able to create immersive, feature-rich search experiences for my applications that feature helpful facets, in-line highlighting, and predictive results as user types."
"The product is pretty resilient."
 

Cons

"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."
"The solution should improve the recovery aspects that it has on offer."
"The price of the solution can be expensive."
"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."
"Maybe they are common in Egypt, but you should make a request on Amazon to create a function to monitor CPU performance, memory, and files. It is very difficult in AWS. I would tell them it should be simple, just drag and drop. I think they could develop this option so we can drag and drop to monitor performance of the processor and memory."
"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."
"I do not have any suggestions for improvements at this time."
"Security is a concern but they're working on it."
"It would be good if the site found a better way to filter things based on subscription."
"The pricing is room for improvement."
"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."
"The after-hour services are slow."
"We used the semantic search capabilities of Azure AI Search, but we haven't gotten good results in the semantic search."
"The solution's stability could be better."
"For availability, expanding its use to all Azure datacenters would be helpful in increasing awareness and usage of the product.​"
"Adding items to Azure Search using its .NET APIs sometimes throws exceptions."
 

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."
"I'm not sure how much we pay a year. It might be around $30,000 a year."
"In comparison to IBM and Microsoft, the pricing is more favorable."
"Our license costs around $4,000 per month."
"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."
"There was no license needed to use this solution."
"The solution is affordable."
"I think the solution's pricing is ok compared to other cloud devices."
"The cost is comparable."
"I would rate the pricing an eight out of ten, where one is the low price, and ten is the high price."
"For the actual costs, I encourage users to view the pricing page on the Azure site for details.​"
"​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."
