>
> The MultiReader statically returns FALSE on any isOptimized() call.
> This makes it unusable as the source index for an InstantiatedIndex, which checks initially if the source index is optimized and aborts if not.
> The attached patch iterates all sub readers and returns TRUE if all of them are optimized.
