the kind of approach Yonik described works well when you really want the "boosted" documents (ie: ads, promoted products, etc) to be inlcuded in the main paginated flow of results, regardless of how many there are. if you want them to be broken out (like the ads google shows in the right nav of their pages) so that they aren't affected by pagination or sorting changes; or if you want a limited number to appear (ie: bubble the 3 highest scoring promoted products up to the top, but leave the rest of the promoted products where they are in the normally sorted list) then i don't know any way arround this except executing two searches. I've typically done it by making two Solr requests from the client, but you could also do this will a custom request handler that included two DocLists in the results. (now that you can progromatically modify/override the params of a SolrQueryRequest, it would be really easy to write a subclass of any existing request handler that first did the "promo" search, and then delegated to the super class with "fq" params telling it to ignore the results you've already included) -Hoss
