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.

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 product is scalable with good performance."
"Decision-making has become much faster due to real-time data and quick responses."
"The most valuable features are the ease and speed of the setup."
"We had many reasons to implement Elasticsearch for search term solutions. Elasticsearch products provide enterprise landscape support for different areas of the company."
"The most valuable feature of Elastic Enterprise Search is the Discovery option for the visualization of logs on a GPU instead of on the server."
"Elasticsearch includes a graphical user interface (GUI) called Kibana. The GUI features are extremely beneficial to us."
"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."
"The initial installation and setup were straightforward."
"Microsoft FAST is quite robust. Our clients are quite happy with it."
 

Cons

"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."
"The upgrade experience and inflexibility with fields keeps Elastic Search from being a perfect 10."
"What they need is to be more transparent about the actual setup of the cluster and the deployment process."
"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."
"They're making changes in their architecture too frequently."
"Something that could be improved is better integrations with Cortex and QRadar, for example."
"It was not possible to use authentication three years back. You needed to buy the product's services for authentication."
"The metadata gets stored along with indexes and isn't queryable."
"If there is any change in a system or a configuration or an update, we might face some issues."
 

Pricing and Cost Advice

"we are using a licensed version of the product."
"The solution is free."
"The pricing model is questionable and needs to be addressed because when you would like to have the security they charge per machine."
"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 Elastic Enterprise is very, very competitive."
"We are using the free version and intend to upgrade."
"This is a free, open source software (FOSS) tool, which means no cost on the front-end. There are no free lunches in this world though. Technical skill to implement and support are costly on the back-end with ELK, whether you train/hire internally or go for premium services from Elastic."
"The basic license is free, but it comes with a lot of features that aren't free. With a gold license, we get active directory integration. With a platinum license, we get alerting."
