Yes, that is exactly what I want to do ! My external system gives me sell rate/Top N Selling books matching the user terms (query)
I don't know what is the best way: Storing sell rate into lucene Fields of the documents... (multiple combination) and sort by this field, or doing something like you said: "adding an optional clauses to your query for each of your N productIds"... but I don't really know how to do this... Any sample code exemple ?
