I’m looking for more details regarding the use of the “filter” attribute and getting a list of HOSTS under a spceific cluster.

I have tried making the call using the following data but it returns the hosts for all the clusters instead of the specified one

{
  "kind": "host",
  "filter": “cluster=in=randomplaceholderclusterid",
  "length": 1,
  "offset": 0
}

Any help on this would be appreciated. 

Also, is there additional documentation on the FIQL filtering options in the REST api?

Hoping for a quick response,

Thanks!
