How to display other fields than Title in the suggestions?

I understood my problem: I was using "Display Live results", which offers only options to use the entity label or a display mode of the entity.
I use now "Retrieve from server", which is a better option for me. The problem now is that I'd like to suggest only complete names, and not names based on different fields. If I use for autocomplete the fields indexed as "fulltext", I get suggestions for entities which do not exist. Example: I have one entity with Title = "Abiotrophia defectiva" and FieldA = "Streptococcus defectivus". In the search field I get suggestions like "abiotrophia defectivus", which is wrong and doesn't return any result. The best option would be to use for autocomplete the fields indexed as "String". But this type of index field is not available in the options of the "Retrieve from server" suggester.

It seems like what you want is “Display live results”, not “Retrieve from server”. (You want the autocomplete list results, not suggested search keywords – correct?) For displaying something other than the title, you can either create a new display mode for showing just that one field, or use hook_search_api_autocomplete_suggestions_alter() to override the display value.

I hope this helps. Otherwise, please feel free to re-open this issue.
