Diving into the OpenShift Container Platform (OCP) is a challenge. One primary objective of our client was to host a Micro-Services Architecture (Spring Boot) on a Micro-Services Platform. Therefore OpenShift was acquired.

From data type changes to the index structure changes and deprecations, from Transport to REST client and so one. One of those changes that would influence your system, is the scoring algorithm evolution. In this blog, we demonstrate the impact on relevance and scoring if the Elasticsearch changes its algorithms under the hood between major versions. We will show it practically, using a small dataset. If the scoring feature of Elasticsearch…
