# Domain Filtering

> Restrict or exclude specific domains from search results

Snippex lets you control which domains appear in your results using `include_domains` and `exclude_domains`.

## Include specific domains

Use `include_domains` to restrict results to a set of trusted sources:

```json theme={null}
{
  "query": "climate change effects on agriculture",
  "include_domains": ["nature.com", "science.org", "who.int"]
}
```

Only results from the listed domains will be returned.

## Exclude specific domains

Use `exclude_domains` to filter out domains you don't want:

```json theme={null}
{
  "query": "best programming languages 2024",
  "exclude_domains": ["reddit.com", "quora.com"]
}
```

## Combine both

You can use `include_domains` and `exclude_domains` independently. They cannot be combined in the same request (include takes precedence if both are provided).

## Notes

* Provide bare domain names without `https://` or trailing slashes: `"nature.com"` not `"https://www.nature.com/"`
* Subdomains are matched: `"bbc.com"` will include `"news.bbc.com"`
* An empty array (`[]`) means no filter is applied (default behavior)
