Hi Dave, you are right with both aspects: we cannot scale this index and we cannot guarantee that people use only the index. The same holds for my collation example though, and here people were willing to do testing etc. the question of testing probably goes to Tadej, who is the one in the group using the resources anyway (without an index or not)?
