Re: Feature & design question: use autocomplete to search on 2
different fields, and return 2 different data groups
You might be able to do something like append "tags" to the suggestions.
So, you'd actually index
pizza:cat
pizza hut:business
Then you app gets these back and can display them however is most pleasing
to the user.
But.... consider that all autosuggest is doing is searching the indexed
terms. So here in michigan we have "Cottage Inn Pizza". Since it doesn't
start with "pizza", it wouldn't be returned when doing an autosuggest on
"piz". You'd have to do something like index this "pizza cottage
inn:business:Cottage Inn Pizza" in order to get back something sensible to
display....
If your speed is sufficient, you could always to a straight Solr query and
use grouping. In that case you'd have to do something like index a field
"suggest_type" and group on that field. But this may be too slow....
