@u007 how would this work? The reason we use map is to match var name to value. If we send a slice, then we would need to create var-names. Correct? Please show a use case of this.

hi @srfrog ,  
maybe something like

```auto
uid_in(field, ["0x878110", "0x06"])

```

or in go

```auto
values = []string{"0x878110", "0x06"}
uid_in(field, $values)

```

it is already possible to do

```auto
follows @filter(uid_in(~follows, [0x1d, 0x1e, 0x20, 0x21])) 

```

unfortunately, you can’t do:

```auto
follows @filter(uid_in(~follows, $uids)) 

```

with multiple uids. Pinging @anurags92

* * *

you can do

```auto
follows @filter(uid_in(~follows, [$uids]))
#Message: : Value "0x1d, 0x1e, 0x20, 0x21" in uid_in is not a number

```

but even so, you can add multiple uids in the GraphQL Query.

Also, it is not possible to force the pseudo-array in the GraphQL Query:

```auto
query query($uids: string = "[0x1d, 0x1e, 0x20, 0x21]") {
  query(func: has(follows)) @cascade
    {
    uid
      follows @filter(uid_in(~follows, $uids)) 
      {
        uid
      }
  }
}

```

Hello digger from the future.  
The best you can do to workaround this is

```auto
query query($uids: string = "[0x1d, 0x1e, 0x20, 0x21]") {
   
  Uvar as (func: uid($uids))

  query(func: has(follows)) @cascade
    {
    uid
      follows @filter(uid_in(~follows, uid(Uvar))) 
      {
        uid
      }
  }
}

```

Multiple blocks and use uid()

Or… _sigh_  
Just insert uids into query string with string format in your preferred language
