Logging and vector search have transformed observability and empowered reliable ai agents
Elastic Search is not specifically being used for certain purposes. I deploy Elastic Search database on the cloud and use cloud services so that nobody can attack. However, I do not use Elastic Search to resolve attack issues. The basic main purpose of Elastic Search, as of now, I feel it can do more in the AI area. Sometime I saw that when I am developing RAG and have to generate the embeddings, which I call metadata, sometimes it tries to fail. That durability or issue handling should be improved, but apart from that, I did not find anything as of now. As per my use case, whatever I am using seems pretty good. Apart from that, some definitely improvement will be there. One improvement is that it should be faster. Whenever I am searching any logs, it takes much time. For example, if I open my log in Notepad or a similar tool, I can search the text within a second. With Elastic Search, it takes a little bit of time, ten to fifteen seconds. That can be improved. Sometimes, engineers take time to assign when I create a ticket.

Robust solution with good value
Microsoft FAST is quite robust. Our clients are quite happy with it. For other users who already have a solution in place, we recommend Microsoft FAST because it is more compatible and you can organize the solution with Microsoft components. If you are with any other third party, there could be a chance that the required output is not what you would expect. But with Microsoft, it will work better. It is compatible with the older generation systems, so you can offer it. On a scale of one to ten, I would give Microsoft FAST an eight because I'm quite comfortable with it.

Quotes from Members

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

Pros

"The speed with which Elastic Search is able to search through all of the documents we place into it is quite remarkable, as we search through 65 billion documents in less than a second in most cases, on a constant consistent basis."
"All the quality features are there. There are about 60 to 70 reports available."
"If you decide to run with it, the performance and the result can be very satisfactory."
"We have many advantages from the features of Elasticsearch, and we have enough possibilities and features with Elasticsearch for our business requirements."
"Elastic Search is much better, and Kibana is also invaluable."
"The product is scalable with good performance."
"The solution is very good with no issues or glitches."
"The solution has good security features. I have been happy with the dashboards and interface."
"Microsoft FAST is quite robust, our clients are quite happy with it, and for other users who already have a solution in place, we recommend Microsoft FAST because it is more compatible and you can organize the solution with Microsoft components."
"Microsoft FAST is quite robust. Our clients are quite happy with it."
"Microsoft FAST is a really amazing search application."
 

Cons

"The documentation regarding customization could be better."
"Elastic Search should provide better guides for developers."
"The real-time search functionality is not operational due to its impact on system resources."
"Elastic Search needs to improve authentication. It also needs to work on the Kibana visualization dashboard."
"The solution has quite a steep learning curve. The usability and general user-friendliness could be improved. However, that is kind of typical with products that have a lot of flexibility, or a lot of capabilities. Sometimes having more choices makes things more complex. It makes it difficult to configure it, though. It's kind of a bitter pill that you have to swallow in the beginning and you really have to get through it."
"This is not exactly a stable solution, which is why we are considering another compatible tool, and whether we go on with Elasticsearch or change it."
"There should be more stability."
"Elasticsearch could be improved in terms of scalability."
"If there is any change in a system or a configuration or an update, we might face some issues."
"We do get support from Microsoft, but the response is quite slow."
 

Pricing and Cost Advice

"The premium license is expensive."
"we are using a licensed version of the product."
"​The pricing and license model are clear: node-based model."
"The solution is affordable."
"The tool is not expensive. Its licensing costs are yearly."
"We use the free version for some logs, but not extensive use."
"We are using the free open-sourced version of this solution."
"We are paying $1,500 a month to use the solution. If you want to have endpoint protection you need to pay more."
