There are a few ways to combine searches, but the preferred way uses the general form:

(<<query 1>>) OR (<<query 2>>) | stats values(*) as * by <<common fields>>

The join command should produce the format you seek, but you'll be unhappy with the performance. That's why the previous method I suggested is preferred.

<<query 1>> | join <<common fields>> [ <<query 2>> ]

The indexed events are not combined. Indexed data is never changed so the events will forever remain separated. All we can do is correlate data from the indexes and display it in an appropriate format. You can, however, write the correlated data to a summary index using the collect command then fetch the events in the summary index to see a combined event.

My first answer said how to create a table with events of the same job from both indexes, but then you said you don't want a table.
