Function SelectSearchChain

cli/plugins/builtin_websearch.go:256–261

SelectSearchChain returns the ordered list of providers to try. An unset override → auto mode (DDG first → SearxNG if configured). An explicit override moves the named provider to the front and keeps the rest as fallbacks — so even a forced choice degrades gracefully.
