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.

Search performance has transformed large-scale intent discovery and hybrid query handling
While Elastic Search is a good product, I see areas for improvement, particularly regarding the misconception that any amount of data can simply be dumped into Elastic Search. When creating an index, careful consideration of data massaging is essential. Elastic Search stores mappings for various data types, which must remain below a certain threshold to maintain functionality. Users need to throttle the number of fields for searching to avoid overloading the system and ensure that the design of the document is efficient for the Elastic Search index. Additionally, I suggest utilizing ILM periodically throughout the year to manage data shuffling between clusters, preventing hotspots in the distribution of requests across nodes.

Quotes from Members

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

Pros

"The customer engagement was good."
"The product is pretty resilient."
"The amount of flexibility and agility is really assuring."
"Creates indexers to get data from different data sources."
"The product is extremely configurable, allowing you to customize the search experience to suit your needs."
"Offers a tremendous amount of flexibility and scalability when integrating with applications."
"The search functionality time has been reduced to a few milliseconds."
"Azure Search is well-documented, making it easy to understand and implement."
"It gives us the possibility to store and query this data and also do this efficiently and securely and without delays."
"The best feature of Elastic Search that I appreciate is its monitoring capability."
"The most valuable features of Elastic Enterprise Search are it's cloud-ready and we do a lot of infrastructure as code. By using ELK, we're able to deploy the solution as part of our ISC deployment."
"The initial setup is very easy for small environments."
"The most valuable feature is the out of the box Kibana."
"Elastic Enterprise Search is scalable. On a scale of one to 10, with one being not scalable and 10 being very scalable, I give Elastic Enterprise Search a 10."
"The most valuable feature of the solution is its utility and usefulness."
"I find the solution to be fast."
 

Cons

"The pricing is room for improvement."
"The initial setup is not as easy as it should be."
"It would be good if the site found a better way to filter things based on subscription."
"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."
"Adding items to Azure Search using its .NET APIs sometimes throws exceptions."
"The solution's stability could be better."
"They should add an API for third-party vendors, like a security operating center or reporting system, that would be a big improvement."
"The after-hour services are slow."
"Elastic Enterprise Search could improve the report templates."
"What they need is to be more transparent about the actual setup of the cluster and the deployment process."
"Improving machine learning capabilities would be beneficial."
"We'd like to see more integration in the future, especially around service desks or other ITSM tools."
"The documentation regarding customization could be better."
"Elastic Enterprise Search could improve its SSL integration easier. We should not need to go to the back-end servers to do configuration, we should be able to do it on the GUI."
"Better dashboards or a better configuration system would be very good."
"Kibana should be more friendly, especially when building dashboards."
 

Pricing and Cost Advice

"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."
"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."
"I would rate the pricing an eight out of ten, where one is the low price, and ten is the high price."
"An X-Pack license is more affordable than Splunk."
"Elastic Search is open-source, but you need to pay for support, which is expensive."
"Although the ELK Elasticsearch software is open-source, we buy the hardware."
"The version of Elastic Enterprise Search I am using is open source which is free. The pricing model should improve for the enterprise version because it is very expensive."
"The price could be better."
"The tool is not expensive. Its licensing costs are yearly."
"The premium license is expensive."
"We are using the free version and intend to upgrade."
