In Lucene's term that would mean that an index copy is present on all
nodes (not store in Infinispan necessarily) and all changes are passed
and executed on all nodes (being passed in total ordering via JGroups).
Ah, that changes the game ! I thought that the index is some kind of
metadata, present on every node. Of course, if that'snot the case, then
SEQUENCER makes no sense...
