Search Completion

Vimium supports search completion for custom search engines (not for the default search engine). Search completion is activated whenever the search URL of a custom search engine matches one of the completion engines built into Vimium.

To activate search completion, type o to activate vimium bar and then type the search completion keyword as defined in settings (such as 'g') and press space.

Here are a couple of examples of how the vomnibar looks with search completion.

Contributing completion engines

PRs contributing completion engines are most welcome. Completion engines are not hard to write. Here's an example:

class DuckDuckGo extends RegexpEngine
  # Example search URL: https://duckduckgo.com/?q=%s
  constructor: -> super "^https?://([a-z]+\.)?duckduckgo\.com/"
  getUrl: (queryTerms) -> Utils.createSearchUrl queryTerms, "https://duckduckgo.com/ac/?q=%s"
  parse: (xhr) ->
    suggestion.phrase for suggestion in JSON.parse xhr.responseText

Completion for default search

Search completion is available for custom search engines only, not for the default search engine. Nevertheless, you can get search completion for your default search engine by adding it also as a custom search engine. For example:

g: https://www.google.com/search?q=%s Google
