In this series of guides we will go through typical cases of using Metarank to improve the relevance of your search engine.

There are two main approaches to search reranking:

  • Zero-shot: using generic approaches not fine-tuned on your dataset and visitor behavior. This does not require any telemetry collection and is a good starting point.

  • Learn-to-Rank: adapt ranking to the dataset and visitor behavior. Can yield better quality, with the drawback of requiring proper visitor analytics.

If you're not familiar with concepts of re-ranking and Metarank, start with these intro guides to get better understanding about how things work:
