Like @marmistrz I'd also prefer

Type 'keyword'

Google search: 'keyword
Startpage search: 'keyword'
Wikipedia search: 'keyword'

// and so on,

Like in Firefox on Jolla. Select one of the search engine options.

However I have settled for easy DuckduckGo:

By replacing by entering about:config in MicroB

and replacing keyword.url string with

https://duckduckgo.com/html/?q=

This gives you the java free version.
