Autocomplete Search Feature Request

Here is my feature request.

An improved search function to filter by Custom Post Type, Custom Taxonomy, Category, Tags – and all selectively. In other words, where in settings a user can specify what the search should actually index. Then display the results in AutoComplete.

Here is a feature I really like

The idea comes from TripAdvisor. I have a similar setting where if a user wants to search for Phuket, then I would like to display my posts organised as in the image above.
