Sorting a large set is costly, the more fields you sort on, the more memory is consumed (and likely cached).
If i remember correctly the result set will be ordered according to Lucene DocID's if there's nothing to sort on. If i read correctly, you don't want to specify those fixed sort parameter for every query right? You can simply add the parameter as default (or constant (= invariant)) in your request handler configuration in solrconfig. > Au contraire, I have almost 4 million documents, representing businesses in > the US.
