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%)
