# 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%)
