arules command returns no output

[iKate]

Hi,
Basing on customers' purchases I'd like to make a proposition of what item can be probably purchased if a user had previously purchased itemX.
Seems the command arules can help with this but I got no reults using it.

My dataset is a list of transactions with major fields that I intended to use: user_id and item_name

source=transactions | arules user_id item_name

Am I misusing the command? Or is there another way to get the desired information in splunk?

[heshamzaid]

put the search in the smart mode

I'd like to bump this as well.

[aljohnson_splun]

bump. I'm confused too.

Can you share some sample of your data ?
