Using a single node Solr instance, I need to search for, lets say, electronics items & grocery items. But I never want to search both of them together. When I search for electrnoics I don't expect a grocery item ever & vice versa.
Should I be defining both these document types within a single schema.xml or should I use different collection for each of these two(maintaining separate schema.xml & solrconfig.xml for each of two) ? I believe that if I add both to a single collection, without sharing fields among these two document types, I should be equally good as separating them in two collection(in terms of performance & all), as their indexes/filter caches would be totally independent of each other when they don't share fields?
