How can I provide an autocomplete filter for tags in a Search API view? I'm working to create a Search API view. I have an exposed filter that's a fulltext search filter. I'd like to expose another filter that works similar to the exposed entity reference, which allows users to reference multiple tags, separated by commas; the field will then autocomplete the entered value.  

Is there a way to achieve this using the Search API Views and the Search API Autocomplete modules?  As far as I can see, there isn't a way to autocomplete multiple words/phrases, instead of just the first word/phrase.
Add the datasource (entity reference) as a exposed filter. 


Check the "allow multiple selections". 



Now, the user can add comma seperated tags (with autocompletion):
