What it is
The CSS selector configuration that binds the Autocomplete widget to the theme’s search input(s), enabling the widget to listen for keystrokes and display suggestions.
Why it matters
A correct selector is required for Autocomplete to initialize reliably across header, footer, mobile drawer, and other search input locations. Wrong selectors cause no-initialization or multiple bindings.
How to configure
Inspect your theme to locate the search input element(s) (e.g., input[name="q"], form[action="/search"] input).
Paste a stable, specific selector into Search Field Integration (case-sensitive).
If multiple inputs exist, add selectors for each or use a common parent selector.
Save and test on pages where each input appears.
