I have multiple indexes, possible to have one search bar with a dropdown to select which index you would search?

Since the Search API module in general doesn’t provide any search pages, blocks or other user-facing UI, I don’t think adding something like this to this module would make much sense.
Since all your search pages are views there might be some Views-related contrib module that already lets you do something like this – enter something in a text field and than submit to one of several views at the user’s choice. However, I guess this feature mostly makes sense for searches, so not sure if it exists yet.

I, in any case, don’t know of something like that, so if you cannot find anything you’d have to write some code for this yourself. The code would be pretty simple – a block with a form, containing a textfield and a dropdown, that submits the entered keyword to the selected page. But only trivial if you are a developer, of course.
