Just to complete my prev use case, in case no direct way is possible in SOLR to sort on a field in a different core, is there a way to embed the tagValue of a product dynamically into the results (the storeid will be passed at query time. So query the product_tags core for that product+storeid and get the tagValue and embed it into the product results probably in the "process" method of a custom component ... in the first place I believe we can add a value like that to each result doc). But then how can we sort on this value as I am now working on the results which came out after any initial sort was applied and can we re-sort at this very late stage using some java sorting in the custom component.
