Many popular search dropdowns on sites like Amazon (example image) use autosuggested words along with grouping (Field Collapsing in Solr).
While I can replicate the same functionality in Solr using two requests (first to obtain suggestions, second for the actual query using the most probable suggestion), I want to know if this can be done in one request itself.
I understand that there are various ways to obtain suggestions (term component, facets, Solr's inbuilt (Suggester), and I'm open to using any one of them, if it means I'll be able to get everything (groups + suggestions) in one request.
