Varun Thacker commented on SOLR-6841:
-------------------------------------
This is cool!
While playing around I observed that when there are no segments in the index,
the Segments Info page says:
Size 0
Deletions: NaN%
In the future it would be awesome if we could click on a segment we could get
more granular information about it like the number of fields in the segment,
number of terms in that field, memory consumed by the segment etc.

> We find it useful to tune merge policy not blindly but looking on segment
> size and fill ratio.
> We're working on a patch that adds a tab to admin page with McCandless-style
> of segment visualization.
> Draft UI is attached (currenly as part of admin.extra).
> Please share your ideas if it's ok to put the code in core admin.
