 == searchengines
 Definitions of search engines which can be used via the address bar.
 The searchengine named `DEFAULT` is used when `general -> auto-search` is true and something else than a URL was entered to be opened. Other search engines can be used by prepending the search engine name to the search term, e.g. `:open google qutebrowser`. The string `{}` will be replaced by the search term, use `{{` and `}}` for literal `{`/`}` signs.
