"Unmatched Query Power and Speed for Scalable AI-Driven Search"
4.5/5
What do you like best about Elasticsearch?

1. Query Flexibility and Power (DSL): The expressive power of the Query DSL is unmatched. We can easily combine exact filtering (e.g., in stock > 0), range queries (e.g., voltage: [3V TO 5V]), and semantic relevance ranking (e.g., full-text match for 'low power') in a single lightning-fast query. This is essential for AI-driven component matching.

2. Speed and Scalability: For our users, sub-second response time is non-negotiable. Elasticsearch's distributed architecture and inverted index structure ensure that even as our component catalog scales into the tens of millions, performance remains consistently fast. Review collected by and hosted on G2.com.

What do you dislike about Elasticsearch?

1. Initial Learning Curve: While the flexibility is fantastic, the initial setup—particularly defining efficient mappings, indexing strategies, and understanding the nuances of the Query DSL—involves a steep learning curve. The barrier to entry for a small team compared to a managed SQL service is significant.

2. Cost at Scale (Self-Hosted vs. Cloud): While self-hosting offers performance control, the resource consumption for high-speed indexing and large clusters can become substantial, making cost optimization a constant operational task. The various cloud offerings help, but this remains a key consideration for startups managing costs. Review collected by and hosted on G2.com.

"Blazing-Fast Metrics at Scale with Elasticsearch"
4.5/5
What do you like best about Elasticsearch?

Elasticsearch is well suited to a high velocity, high volume, low datastore scenario. It renders very quickly a big load of metrics in a meaningful, human readable fashion. Its speed is a big plus for repetitive requests. Review collected by and hosted on G2.com.

What do you dislike about Elasticsearch?

As your dataset grows, the hardware requirements for running Elasticsearch grow with it. For companies on a limited budget, those increasing infrastructure needs can quickly become financially overwhelming. Review collected by and hosted on G2.com.

"Exceptional Documentation, Intuitive UI, and Outstanding Support"
5/5
What do you like best about Elasticsearch?

I appreciate the wealth of documentation available which makes it easier to implement solutions on my own. Their AI support option is also excellent and often times I do not need to lodge an actual support ticket as the AI recommendations resolved my issue.

The Elastic UI is clean, intuitive and easy to use.

I find the Dev Tools feature within Elastic to be really useful as most of my updates are managed via Elastic ESQL queries which enables me to keep my changes within a repo.

Setting up SSO via Entra ID was fairly straightforward. Ability to do the role mappings for entra ID groups to Elastic roles was easy to do via the UI and also via the Dev Tools.

Customer Support is excellent, they work with you until your issue is fully resolved.

Elastic can be purchased via AWS Marketplace which makes billing seamless if you already work with AWS.

The Elastic infrastructure is scalable and also very resilient. If there are load issues or similar it will scale up as required.

The web crawler is also easy to configure and update directly in the UI.

Search queries are very performant (milliseconds usually). Review collected by and hosted on G2.com.

What do you dislike about Elasticsearch?

From version 9, you will have to self-manage your Elastic web crawlers which shifts the responsibility on the customer to provide the infrastructure that supports the web crawler. There is also the ongoing support that comes with this too.

It seems to be focusing more and more on its core feature i.e. search, and not so much on user-focused features tailored for non-tech business users.

It would be great if it provided repos with examples to easily setup frontend search experiences. Review collected by and hosted on G2.com.

"Powerful Search Platform for Enterprise-Scale Operations"
5/5
What do you like best about Elasticsearch?

What I like best about Elasticsearch is its powerful search and aggregation capabilities combined with high performance at scale. We support over 100 customers who use it daily in their operations, and Elasticsearch consistently handles large data volumes with fast response times.

From a support perspective, features like detailed query capabilities, clear APIs, and strong integration within the Elastic Stack significantly improve our workflow. Kibana dashboards help us quickly analyze customer issues, review logs, and identify performance bottlenecks without needing custom tools. This often reduces troubleshooting time from hours to minutes.

An unexpected benefit has been how flexible and scalable the platform is across different customer environments. It allows us to support diverse use cases while maintaining a relatively standardized architecture. Review collected by and hosted on G2.com.

What do you dislike about Elasticsearch?

One of the main challenges with Elasticsearch is the complexity of configuration and tuning, especially in larger or high-availability clusters. For customers without deep expertise, settings around JVM tuning, shard allocation, and performance optimization can be difficult to manage. This often increases the support workload and extends troubleshooting time.

Version upgrades can also be demanding. Breaking changes between major versions and strict compatibility requirements sometimes require careful planning and additional testing, which impacts customer environments and maintenance windows.

Customers often ask about the possibility of reverting to the previous version, but this is not possible.

In such cases, we have to come up with our own workarounds.

Improved backward compatibility, clearer upgrade paths, and more built-in automated diagnostics for cluster health and performance tuning would significantly reduce operational overhead for both customers and support teams. Review collected by and hosted on G2.com.

"Powerful and Scalable Search Engine with Excellent Performance"
5/5
What do you like best about Elasticsearch?

What I like most about Elasticsearch is its speed and flexibility. It can handle very large volumes of data while still delivering fast and accurate search results. The query DSL is powerful and allows complex filtering and aggregation, which makes it suitable for many use cases beyond simple search. It also scales very well and integrates easily with other tools in the Elastic ecosystem. Review collected by and hosted on G2.com.

What do you dislike about Elasticsearch?

The main downside is the learning curve. Getting the most out of Elasticsearch requires a good understanding of mappings, indexing strategies, and performance tuning. It can also be resource-intensive, especially for smaller teams or projects, and may feel overkill for simple search needs. Review collected by and hosted on G2.com.

"Indispensable for central log analysis"
5/5
What do you like best about Elasticsearch?

I think it's great that Elasticsearch provides a central hub for logs, metrics, and alerting, which didn't exist before. I especially like that it's easy to search, visualize, and build alerting on the data once it's there. The initial setup in the cloud was also really easy. Review collected by and hosted on G2.com.

What do you dislike about Elasticsearch?

Ensuring that the data ends up in the correct indices/namespaces is labor-intensive, as is managing data retention through lifecycle policies. This could be made simpler. Review collected by and hosted on G2.com.

"Elasticsearch – Fast, Flexible, but Needs Care"
4.5/5
What do you like best about Elasticsearch?

I’ve been using Elasticsearch for a while now, and the first thing that consistently impresses me is its speed. No matter if I’m searching through logs, text, or analytics data, it delivers results incredibly quickly once it’s properly configured. I also like how well it scales; adding more nodes allows it to handle larger and larger workloads smoothly.

I also appreciate its flexibility. Elasticsearch supports everything from simple keyword searches to more advanced aggregations, autocomplete, and even fuzzy matching. Review collected by and hosted on G2.com.

What do you dislike about Elasticsearch?

Elasticsearch is not particularly plug-and-play. There is a noticeable learning curve, especially when it comes to configuring clusters, tuning shards and replicas, and maintaining stable performance as your data volume increases. If you don't size your setup correctly, it can also become quite resource-intensive. Review collected by and hosted on G2.com.
