One solution is to keep meta-data in your index. Remember that documents do not all have to have the same field. So you could index a document with a single field "metadatanotafieldinanyotherdoc" that contains, say, a list of all of your clusters and their boosts. Read this document in at startup time and cache it away in your server. Thereafter, you have a set of boosts that can be applied at query time.
Of course this useless if you wanted to boost at index time. But I know of no way to change the boost of a document without deleting and readding it with the new boost.
