> IndexOrDocValuesQuery allows to combine costly range queries with a selective lead
iterator in an optimized way. However, the range query at some point gets cached by a querying
thread in LRUQueryCache, which negates the optimization of IndexOrDocValuesQuery for that
specific query.
> It would be nice to see an asynchronous caching implementation in such cases, so that
queries involving IndexOrDocValuesQuery would have consistent performance characteristics.
