#### **Resource uploading parameters**

#### **Chunk Size**

When you upload a resource, its content is split into chunks.

{% hint style="warning" %}
If you upload a resource with the **No Split** chunking strategy, the whole file is treated as one chunk. This can fail if that chunk exceeds the input length limit of **2000** tokens.
{% endhint %}

* **Max value**: 200 – 2000 tokens
* Defines the maximum size of a single chunk of text.

#### **Chunk Overlap**

Chunk overlap means that consecutive text chunks share some of the same content, so important information that sits at the boundary between chunks is not lost.

* **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%.

{% hint style="info" %}
Chunk 1: "The company was founded in 2010 by **John Smith.**"\
Chunk 2: "**John Smith.** It expanded to Europe in 2015."

\
In this case, "John Smith." is the chunk overlap between the first and the second chunk
{% endhint %}

{% hint style="warning" %}
With a chunk size of 1000 and 25% overlap, each chunk still contains a total of 1000 tokens of which 250 tokens are the repeated ones the adjacent chunk.
{% endhint %}

#### **Improving retrieval of resources for the AI reply**

**Limit** defines how many candidate chunks are retrieved.&#x20;

**Score Threshold** removes candidates whose relevance score is below a minimum value.

#### **Limit**

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

#### **Score Threshold**

**Score Threshold** is the minimum relevance score a chunk must have to be included in the results.

* **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.
