How to customize stats using simple math?

If I wanted a count of all the events in all my indices, I can just do:
index=* | stats count, which just returns a single number in a single row with this value.

But say I wanted to customize the stats function - say I want to add 2 to the count returned:
index=* | stats count+2 is invalid.

How can I customize an aggregate statistics function with simple math operations?

index=* | stats count AS count| eval count = count + 2

Try this

| metasearch index=*
| stats count 
| eval count='count'+2

You need to use an eval to do basic mathematical calculations

Metasearch will look at your index time fields and search 10x faster than doing index=*

I downvoted this post because refusing to accept a correct answer leaves unanswered spam on the board.
