Sorting by a function query: http://wiki.apache.org/solr/FunctionQuery#Sort_By_Function https://cwiki.apache.org/confluence/display/solr/Function+Queries#FunctionQueries-SortByFunction The second URL also shows how to put the results of a function into the search results as a pseudo-field. You do mention that you are talking about summing the values from one field ... if that's not being done with a function query, then this probably does not apply, and I don't know what you'll need.
