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.

Provides quick and easy containerization, but documentation is not very user-friendly
Milvus' documentation is not very user-friendly and doesn't help me get started quickly. Chroma DB provides super user-friendly documentation, enabling new users to get started quickly. Chroma DB's setup doesn't have many dependencies, whereas Milvus usually comes with some dependencies because of the way it needs to be deployed. Unlike Milvus, it's very easy to do POCs with Chroma DB.

Quotes from Members

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

Pros

"On the subject of pricing, Elastic Search is very cost-efficient, as you can host it on-premises, which would incur zero cost, or take it as a SaaS-based service, where the expenses remain minimal."
"The best feature of Elastic Search that I appreciate is its monitoring capability."
"I have found the sort capability of Elastic very useful for allowing us to find the information we need very quickly."
"The most valuable feature of Elastic Enterprise Search is user behavior analysis."
"My favorite feature is the ease of use, particularly in how you integrate the agent; I've been using it since version 7, and we're on version 9 now, and I've seen the progress from using Beats to using the agent, making it so simple today to enroll a server with the Elastic Agent."
"It's a stable solution and we have not had any issues."
"The full text search capabilities in Elastic Search have proven to be extremely valuable for our operations."
"Helps us to store the data in key value pairs and, based on that, we can produce visualisations in Kibana."
"The best feature of Milvus was finding the closest chunk from a huge amount of data."
"Milvus has good accuracy and performance."
"I like the accuracy and usability."
"Milvus offers multiple methods for calculating similarities or distances between vectors, such as L2 norm and cosine similarity. These methods help in comparing different vectors based on specific use cases. For instance, in our use case, we find that the L2 distance works best, but you can experiment with different methods to find the most suitable one for your needs."
"The solution is well containerized, and since containerization is quick and easy for me, I can scale it up quickly."
 

Cons

"I would rate the stability a seven out of ten. We faced a few issues."
"I would like to be able to do correlations between multiple indexes."
"Improving machine learning capabilities would be beneficial."
"Something that could be improved is better integrations with Cortex and QRadar, for example."
"In Elastic Search, the improvements I would like to see require many resources."
"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 would rate technical support from Elastic Search as three out of ten. The main issue is a general sum of all factors."
"New Relic could be more flexible, similar to Elasticsearch."
"I've heard that when we store too much data in Milvus, it becomes slow and does not work properly."
"Milvus' documentation is not very user-friendly and doesn't help me get started quickly."
"Milvus could make it simpler. Simplifying the requirements and making it more accessible. It could be more user-friendly."
"Milvus has higher resource consumption, which introduces complexity in implementation."
 

Pricing and Cost Advice

"The solution is less expensive than Stackdriver and Grafana."
"It can be expensive."
"Although the ELK Elasticsearch software is open-source, we buy the hardware."
"ELK has been considered as an alternative to Splunk to reduce licensing costs."
"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."
"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 tool is an open-source product."
"The pricing model is questionable and needs to be addressed because when you would like to have the security they charge per machine."
"Milvus is an open-source solution."
"Milvus is an open-source solution."
