Configure advanced search and chunk settings for your VARIOS AI instance.
The **Expert Settings** tab is only displayed if you have enabled the
[Expert View](../../usage/account/expert-view) in your account settings.
### Hybrid Search Weighting
Configure the weighting between vector search and full-text search for the hybrid search mode. The sum of both weights should equal 100%.
| Field | Description |
| ----------------------- | ----------------------------------------------------------------- |
| **Vector Weighting** | Weight of the vector search (semantic similarity). Default: `50`. |
| **Full-Text Weighting** | Weight of the full-text search (keyword matches). Default: `50`. |
An even distribution (50/50) is a good starting point. Increase the vector
weighting for semantically demanding searches or the full-text weighting for
exact keyword matches.
### Chunk Configuration
Configure how documents are split into sections (chunks) for processing by the embedding model.
| Field | Description |
| ----------------- | ----------------------------------------------------------------------------- |
| **Chunk Size** | Maximum size of a chunk in characters. Default: `2000`. |
| **Chunk Overlap** | Number of characters that overlap between consecutive chunks. Default: `500`. |
Changes to the chunk configuration may require existing documents in the
knowledge base to be re-embedded. Depending on the amount of data, this can
take time and incur costs.
