To be very clear for rookies like me (because I wasted a lot of time on this) you cannot set an Autocomplete request to return specific types of places.
For example, if you want Autocomplete to return just hospitals, or just restaurants, or just parks, as of April 2022, you can't.
This issue requesting that ability was opened in 2011 and hasn't been handled yet. https://issuetracker.google.com/issues/35820774
You can only set Autocomplete to return classes of places, by setting the type to something in Table 3 here - https://developers.google.com/maps/documentation/places/web-service/supported_types
Table 3 options are:
- geocode
- address
- establishment
- regions
- cities

in the Search Function, in variable search change types field to hospital like:
var search = {
bounds: map.getBounds(),
types: ['hospital']
};
and in the Autocomplete predictions so far only "country" restriction is supported as stated in the documentation:
"componentRestrictions can be used to restrict results to specific groups. Currently, you can use componentRestrictions to filter by up to 5 countries. Countries must be passed as as a two-character, ISO 3166-1 Alpha-2 compatible country code. Multiple countries must be passed as a list of country codes."
https://developers.google.com/maps/documentation/javascript/places-autocomplete
If you would like to add this feature for Autocomplete, there is already a case in the issue tracker where you can add your vote to support this request in:
https://issuetracker.google.com/issues/35820774
