> (Please note that the feature described in LUCENE-2425 is required reading 
> for this issue.) 
> The mirroring split policy builds on the remoting split policy, treating each 
> sub-index as a mirror of the super-index (upon which the split writer is 
> built). The motivation for this policy is to allow a given index to be 
> available on multiple nodes (that define a cluster), which helps to 
> load-balance search requests across the nodes in that cluster, not to mention 
> implement fail-over for index searchers.
> Unlike other mirroring solutions for Lucene, this approach gives users the 
> ability to (a) pick and choose the types of directories underlying the 
> mirror, and (b) add/remove mirrors on the fly. However, note that the latter 
> capability has not yet been implemented, although it will be soon.
