Indexer component

A component that defines how chunks are indexed.

---

An Indexer component indexes chunks and configures their storage formats in the document engine.

Scenario

An Indexer component is the mandatory ending component for all ingestion pipelines.

Configurations

Search method

This setting configures how chunks are stored in the document engine: as full-text, embeddings, or both.

Filename embedding weight

This setting defines the filename's contribution to the final embedding, which is a weighted combination of both the chunk content and the filename. Essentially, a higher value gives the filename more influence in the final composite embedding.

• 0.1: Filename contributes 10% (chunk content 90%)
• 0.5 (maximum): Filename contributes 50% (chunk content 90%)
