Lance Norskog commented on SOLR-1931:
-------------------------------------

The UI should change to a drill-down UI that starts at a fast summary of the 
index schema and fields, then drills down to deep scans of different fields.

LukeRequestHandler shall default to "no fields" instead of "all fields".
LukeRequestHandler shall have a new call that returns a list of fields and 
nothing else.

The Ajax UI would fetch the list of fields and then fetch individual fields as 
is does now.
The Ajax UI would include a button that delves deeper into fields, doing the 
various scans it does now.


> Schema Browser does not scale with large indexes

> The Schema  Browser JSP by default causes the Luke handler to "scan the 
> world". In large indexes this make the UI useless.
> On an index with 64m documents & 8gb of disk space, the Schema Browser took 6 
> minutes to open and hogged all disk I/O, making Solr useless.
