#### **Chunk Size**

* Range: 200 – 32,000 tokens
* Defines the maximum size of a single chunk of text.

#### **Chunk Overlap**

* **Range:** 0% – 25% of the chunk size
* Controls how much of the end of one chunk overlaps with the beginning of the next. Increase above 0% if you want content continuity, up to a maximum of 25%.

#### **Limit**

* **Minimum:** 100 chunks
* Specifies the number of chunks the AI will consider when generating an answer.

{% hint style="warning" %}
This is **not** the exact number of resources used, the final selection is refined using the **Score Threshold**.
{% endhint %}

#### **Score Threshold**

* **Range:** 0.3 – 0.9
* After the system fetches the chunks ( up to the **Limit** ), each chunk is assigned a similarity score based on how closely it matches the query.
* Lower values (e.g., 0.3) allow more chunks to be considered, while higher values (e.g., 0.9) are stricter, only selecting highly relevant chunks.
