Do autocomplete results always match search results?

The products shown in autocomplete results will generally match search results, with a few exceptions:

• In search, we assume the user has entered a complete query, but in autosuggest, we assume a user may continue typing. We adapt the algorithm to take this into account.
• Autocomplete needs the fastest performance, so some products won't match exactly if there are large boosts or buries involved in its ranking calculation (though most signals are accounted for).
