As admin, i should be able to get a report on what is going to be changed when Xray requests a project Reindex

Right now, Xray may suggest users/administration to Reindex data and may tell users that "Xray data may be removed", without telling what is going to be changed.

The idea of this suggestion is to allow users/administration to get a report on which data would be changed so users can backup any information they may want to.
