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

"X-Pack provides good features, like authorization and alerts."
"All the quality features are there. There are about 60 to 70 reports available."
"You have dashboards, it is visual, there are maps, you can create canvases. It's more visual than anything that I've ever used."
"The solution offers good stability."
"The observability is the best available because it provides granular insights that identify reasons for defects."
"The most valuable feature of Elastic Enterprise Search is user behavior analysis."
"Elastic Search, being a vector database, quickly indexes data, allowing for searches based on text and data directly, which I found fascinating."
"I am impressed with the product's Logstash. The tool is fast and customizable. You can build beautiful dashboards with it. It is useful and reliable."
"Microsoft FAST is a really amazing search application."
"Microsoft FAST is quite robust. Our clients are quite happy with it."
"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."
 

Cons

"Apart from the good things, what I would like to see improved or enhanced in Elastic Search is the storage cost."
"I think Elastic Search could be improved by introducing more AI features, particularly for complex queries and aggregator functions to enhance usability and readability."
"The upgrade experience and inflexibility with fields keeps Elastic Search from being a perfect 10."
"We have an issue with the volume of data that we can handle."
"Elastic Search needs to improve authentication. It also needs to work on the Kibana visualization dashboard."
"Its licensing needs to be improved. They don't offer a perpetual license. They want to know how many nodes you will be using, and they ask for an annual subscription. Otherwise, they don't give you permission to use it. Our customers are generally military or police departments or customers without connection to the internet. Therefore, this model is not suitable for us. This subscription-based model is not the best for OEM vendors. Another annoying thing about Elasticsearch is its roadmap. We are developing something, and then they say, "Okay. We have removed that feature in this release," and when we are adapting to that release, they say, "Okay. We have removed that one as well." We don't know what they will remove in the next version. They are not looking for backward compatibility from the customers' perspective. They just remove a feature and say, "Okay. We've removed this one." In terms of new features, it should have an ODBC driver so that you can search and integrate this product with existing BI tools and reporting tools. Currently, you need to go for third parties, such as CData, in order to achieve this. ODBC driver is the most important feature required. Its Community Edition does not have security features. For example, you cannot authenticate with a username and password. It should have security features. They might have put it in the latest release."
"In Elastic Search, the improvements I would like to see require many resources."
"I would like to be able to do correlations between multiple indexes."
"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

"It can be expensive."
"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 of Elasticsearch is fair. It is a more expensive solution, like QRadar. The price for Elasticsearch is not much more than other solutions we have."
"We are using the free open-sourced version of this solution."
"Elastic Search is open-source, but you need to pay for support, which is expensive."
"The premium license is expensive."
"We are using the free version and intend to upgrade."
"This product is open-source and can be used free of charge."
