# How To Do MultiVector Chunk Search

Sometimes we may want to add multiple vectors to our chunk search. 

For this, we can simply use the `/collection/advanced`\_`chunk_search` endpoint. We simply switch out the vector argument and change it into a multivector\_query. 

An example of constructing a chunkvector multi-vector query can be found below: 

```
multivector_query = {
    "chunkvector_1": {"vector": [0.2, 0.5, 0.1], "fields": ["test_chunkvector_"]},
    "chunkvector_2": {"vector": [0.5, 0.2, 0.001], "fields": ["test_chunkvector_"]},
}
```

The only difference between constructing a multivector query for advanced chunk search and advanced search is that the fields will contain `chunkvector` instead of `vector`.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://learn.getvectorai.com/vector-search/searching-with-vector-ai/chunk-search/how-to-do-multivector-chunk-search.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
