Index inspection tool

Hi all,

Is there a tool/plugin or just some API one can use to inspect the index IJ builds? We run into issues now end then with broken completion and/or click-through to code. We have not found any characterizing properties which would allow us to build problematic scenario to base a case on. :(  Show the datastructure state/value could be enough to prove thing do go wrong and give maybe useful info for the devs.

So any toolor doc would be nice! A plugin to give insight into the index @runtime would just be super. Hell even a corruption detection would avoid some frustration.

Regards,

Johan
