I can't see any fields when I access the url link in alert mail of my savesearch? I would like to drill down on a savesearch and not only see the results but also the fields. I no that this was disabled by design for version 4.0.9 and later and also understand that the performance can be degraded but would like to have the process to enabled.
In your savedsearches.conf, add
dispatch.status_buckets=1
to the searches that you want to retain the field summaries for, it can greatly impact the performance by enabling this stanza.
