Could this array appending be made simpler by generating the array in one go?

```ruby
@streams = [
  SearchStream.new(
    "mainstream",
    "General results",
    mainstream_results,
    recommended_link_results),
  SearchStream.new(
    "detailed",
    "Detailed guidance",
    retrieve_detailed_guidance_results(@search_term)),
  SearchStream.new(
    "government",
    "Inside Government",
    retrieve_government_results(@search_term))
]
```
