Elasticsearch offers powerful features for full-text search, but one lesser-known and incredibly useful tool is the Percolator. Unlike traditional search, where you query data, the Percolator flips the paradigm — you store queries and match them against documents as they are indexed.

This article focuses on the lifecycle of a percolator index, especially during document ingestion, and how Elasticsearch validates queries against the current mapping to ensure compatibility.
