Overview

Package serrors holds gosearch's sentinel errors in an internal package.

They live here, rather than in the public gosearch package, so that both the public package and internal packages (httpclient, providers) can return the exact same error values without creating an import cycle: the public package imports internal packages, so internal packages cannot import it back. The public gosearch package re-exports these under its own documented names.

var (
	ErrBlocked           = errors.New("gosearch: request blocked by engine anti-bot system")
	ErrChallenge         = errors.New("gosearch: engine returned a captcha or javascript challenge")
	ErrNoResults         = errors.New("gosearch: no results found")
	ErrUnsupportedEngine = errors.New("gosearch: unsupported engine")
)

These are the canonical sentinel error values. The public gosearch package re-exports them (ErrBlocked, ErrChallenge, ErrNoResults, ErrUnsupportedEngine) with full doc comments; see that package for usage semantics.
