Chrome hack: use DuckDuckGo search engine with POST instead of GET.

POST version of DuckDuckGo in Chrome search

We can now drop the GET version of DuckDuckGo, such as

https://duckduckgo.com/?q=%s

and adopt the POST version below.

javascript:((document) => {
  var meta = document.createElement('meta')
  meta.name = 'referrer'
  meta.content = 'no-referrer'

  var form = document.createElement('form')
  form.method = 'POST'
  form.action = 'https://duckduckgo.com//'
  form.setAttribute('accept-charset', 'UTF-8')

  var input = document.createElement('input')
  input.name = 'q'
  input.value = `%s` (1)

  document.head.appendChild(meta)
  document.body.appendChild(form).appendChild(input)

  form.submit()
})(document)

1. Hence the key word can contain " and ' but no `

minified version

javascript:(a=>{var b=a.createElement('meta'),c=a.createElement('form'),d=a.createElement('input');b.name='referrer',b.content='no-referrer',c.method='POST',c.action='https://duckduckgo.com//',c.setAttribute('accept-charset','UTF-8'),d.name='q',d.value=`%s`,a.head.appendChild(b),a.body.appendChild(c).appendChild(d),c.submit()})(document);
