It’s a text-based search engine database that allows you to index, search, and analyze vast volumes of documents within seconds. The near real-time response is achievable by leveraging a unique indexing algorithm that in addition allows distribution across multiple machines and clusters, to support search at scale.</p> <p>However, performance in terms of query speed and latency is not the only thing you want to have optimized when working with search engine software like Elasticsearch. Retrieving and correctly ranking the relevant documents is a challenge by itself, one that's often viewed as a tradeoff between how fast the results are returned and what’s their relevancy. ES has multiple techniques to improve search relevance ranking, including built in ML features. In this blog post, I’ll demonstrate how you can set up a cluster and apply some methods to control the relevance of the results.</p> <p>Read more here: <a href="https://bigdataboutique.com/blog/optimizing-elasticsearch-relevance-a-detailed-guide-c9efd3">https://bigdataboutique.com/blog/optimizing-elasticsearch-relevance-a-detailed-guide-c9efd3</a></p> elasticsearch opensearch BigData Boutique Wed, 25 Oct 2023 06:48:22 +0000 https://dev.to/bigdataboutique/elasticsearch-monitoring-3764 https://dev.to/bigdataboutique/elasticsearch-monitoring-3764 <p>Elasticsearch is one of the most popular software tools in the industry. It is used for Search, of course, but also for Observability, Security Information and Event Management (SIEM), and in recent Elasticsearch versions, even as a Vector Database.</p> <p>This makes Elasticsearch a critical part of the software stack of many companies. And as such it has to be closely monitored.</p> <p>Here is a thorough review of tools for monitoring Elasticsearch clusters, to help keep them stable and at high performance.</p> <p>Read more here: <a href="https://bigdataboutique.com/blog/elasticsearch-monitoring-choosing-the-right-tool-4c5d17">https://bigdataboutique.com/blog/elasticsearch-monitoring-choosing-the-right-tool-4c5d17</a></p> elasticsearch monitoring elk devops
