Hi @bosseres ,

let me understand: in your events you have many different fields as user1=..., user2=... etc..., is it correct?

how much fields do you have?

are they present in all events or they are only one for each event?

if you have only one field in each event, you could try to search for the content of a lookup where there is a column called "user" containing a list of users, using the coalesce option in the evel command, something lie this:

<your_search>
| eval user=coalesce(user1,user2,user3)
| search [ | inputlookup your_lookup.csv | fields user ]
| ...

Ciao.

Hi @bosseres ,

if you have many fields in the same event, you have to search using the lookup for each field.

Ot there could be a workaround:

<your_search> [ | inputlookup your_lookup.csv | rename user AS query | fields query ]
| ...

Ciao.
