Hi guy, there's not much of a search operation here. Why not store the documents in a key/value store and simply fetch them by matching ids?
Another approach: as there is no query, you could easily partition the set of ids and fetch the results in multiple batches. The maximum number of clauses should be 1024. You can set it to a higher value using the respective method in org.apache.lucene.search.BooleanQuery (I've never done that one before, though). Now, your mileage may vary. What is the idea behind this retrieval? You really want to fetch objects by id? Check out MemcacheDB or Apache Cassandra or Apache CouchDB, depending on your application and the type of information you want to store.
