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

"CDN service reduces latency when accessing our web application."
"Document indexing, text-based search API, and Geospatial searches are all good features."
"I've found the solution to be very scalable."
"In our case, AWS is the best in the market, actually."
"AWS CloudSearch's best features are good performance under high CPU and memory use, and ease of deployment and scaling."
"The quality of the solution is good."
"It will remain alive in the market. The solution will be stable in the market."
"The best feature is its scalability in that Cloud is always on the fly."
"The product is pretty resilient."
"It provides good access capabilities to various platforms."
"The solution's initial setup is straightforward."
"The amount of flexibility and agility is really assuring."
"Usually, that search functionality used to take around 10 secs to search data, and that time has been reduced to a few milliseconds now."
"Azure AI Search has impacted my organization positively with overall time saving and low costs as the main outputs that we get after using it."
"The product is extremely configurable, allowing you to customize the search experience to suit your needs."
"The broad access capability is probably the most valuable feature, as it provides access with hardly any physical infrastructure."
 

Cons

"The solution should improve the recovery aspects that it has on offer."
"A reboot should be enhanced."
"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."
"Latlon data type only supports single value per document. All other types support multiple values. We faced issues with this because we had scenarios where, for each document, we needed to store multiple latlon values for different geographical locations."
"AWS CloudSearch's documentation isn't very clear. Also, the on-premise version of the solution is less stable than the cloud version."
"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."
"Amazon's technical support needs to improve as they only solve about half our problems."
"The pricing is room for improvement."
"It would be good if the site found a better way to filter things based on subscription."
"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."
"For availability, expanding its use to all Azure datacenters would be helpful in increasing awareness and usage of the product.​"
"Azure AI Search could be improved regarding compatibility with Azure Blob Storage in order to keep the prompts and everything that I am using for building the tool safe."
"They should add an API for third-party vendors, like a security operating center or reporting system, that would be a big improvement."
"We used the semantic search capabilities of Azure AI Search, but we haven't gotten good results in the semantic search."
"Adding items to Azure Search using its .NET APIs sometimes throws exceptions."
 

Pricing and Cost Advice

"There was no license needed to use this solution."
"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."
"I'm not sure how much we pay a year. It might be around $30,000 a year."
"Amazon AWS CloudSearch charging is based on how many resources you consume or and the solution is known to be a bit expensive."
"For the actual costs, I encourage users to view the pricing page on the Azure site for details.​"
"The solution is affordable."
"The cost is comparable."
"​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 think the solution's pricing is ok compared to other cloud devices."
"I would rate the pricing an eight out of ten, where one is the low price, and ten is the high price."
