Well It depends upon you searches. If they are not super big OR takes lot of time to execute, you can append results of both using append command and export /email as single CSV.
search 1 | append [search 2]
And you can create a dashboard with two panels, one for each report search and schedule PDF delivery

Yes ,that is when both have same fields in the results,but my searches are totally different from other ,one calculates the average time and the other count of a field,if we do a append it combines the result but it does not have any format and the same is sent when saved and scheduled as report
My requirement is like
1)
|stats count by name
a 20
b 40
c 50
and this is saved as report
2)
|chart count of type
abc 4
qwe 3
and save as report
now these two combine using an append will ultimately combine the results but when you save as report by a csv .the csv does not show seperate results right?
