Well, the original problem statement was that there is a list of doc IDs. On the assumption that these are _lucene_ doc IDs, it's just a matter of turning on the bit for each indicated doc in a relatively small, in-memory structure. This presumably could be done once whenever the original list of doc IDs was generated.
But it's almost certainly going to be cheaper than constructing a large OR clause consisting of thousands of doc IDs...
