Boosted search efficiency through real-time querying and seamless indexing for high-volume product data
We are using AWS for our solutions. In AWS, we are heavily using Redshift and Glue. We focus more on vector searches and boosting the keywords, and all those features we are using heavily. In search, the key parameter that we boost up during indexing is essential. We self-implement Elastic Search in our e-commerce application. We are not currently doing a regex setup for RAG Playground, but there is a plan to do that. We are more into vector searches when it comes to how effectively the hybrid search capability meets our needs for combining traditional keyword and vector searches. Regarding the workflow, we are using the API for real-time inference because lots of data is being loaded at real-time on the application, and it is working well for us. I can definitely recommend Elastic Search to be used wherever you have consumer search capabilities needed in a large or scalable manner because it is very effective. I would rate Elastic Search an eight out of ten.

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

"Data indexing of historical data is the most beneficial feature of the product."
"I find the solution to be fast."
"Using real-time search functionality to support operational decisions has been helpful."
"I appreciate that Elastic Enterprise Search is easy to use and that we have people on our team who are able to manage it effectively."
"The solution is quite scalable and this is one of its advantages."
"We can easily collect all the data and view historical trends using the product. We can view the applications and identify the issues effectively."
"The security portion of Elasticsearch is particularly beneficial, allowing me to view and analyze security alerts."
"The most valuable features are its user-friendly interface and seamless navigation."
"Microsoft FAST is quite robust. Our clients are quite happy with it."
 

Cons

"Machine learning on search needs improvement."
"I found an issue with Elasticsearch in terms of aggregation. They are good, yet the rules written for this are not really good."
"They're making changes in their architecture too frequently."
"I would like to see more integration for the solution with different platforms."
"Performance improvement could come from skipping background refresh on search idle shards (which is already being addressed in the upcoming seventh version)."
"Elastic Enterprise Search can improve by adding some kind of search that can be used out of the box without too much struggle with configuration. With every kind of search engine, there is some kind of special function that you need to do. A simple out-of-the-box search would be useful."
"I have not been using the solution for many years to know exactly the improvements needed. However, they could simplify how the YML files have to be structured properly."
"Elastic Search needs to improve authentication. It also needs to work on the Kibana visualization dashboard."
"If there is any change in a system or a configuration or an update, we might face some issues."
 

Pricing and Cost Advice

"The solution is less expensive than Stackdriver and Grafana."
"This product is open-source and can be used free of charge."
"The cost varies based on factors like usage volume, network load, data storage size, and service utilization. If your usage isn't too extensive, the cost will be lower."
"The solution is not expensive because users have the option of choosing the managed or the subscription model."
"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."
"we are using a licensed version of the product."
"ELK has been considered as an alternative to Splunk to reduce licensing costs."
"It can move from $10,000 US Dollars per year to any price based on how powerful you need the searches to be and the capacity in terms of storage and process."
