Search

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.

Zero-shot re-ranking
