Splunk Search

How to get to a working example of the Map Command?

I am trying:

name=foo minutesago=1 | head 1000 | dedup host | stats list(host) as list | map search="search host=$list$ | head 1"

the "name=foo minutesago=1" search will return a bunch of events from about 8 or 9 hosts. When I run the above search, I get 1 event back. I would expect 1 event from each host, per my understanding of the Map command.

Is there something here I am doing wrong? Could somebody provide a working example of Map in action? I suppose I might be passing the "$list$" variable incorrectly, but the documentation is a bit scant.

EDIT: Working search:

name=foo minutesago=1 | head 1000 | dedup host | map search="search host=$host$ | head 1"

My guess here is that the map command doesn't like the multivalued field that the stats command is outputting. What happens if you remove the stats command from your search?

ah... thats it. So the variable is all the values of a field in the collection of events that you pipe to map.
