Http request to Orchestrator API using 'or' in Endpoint for Queue Items

I am trying to get all the different items with statuses ‘failed’ or ‘abandoned’.

https://XXXX/odata/QueueItems?$filter=QueueDefinitionName eq 'XXXX ’ and Status eq ‘Failed’” - this works

But if I want to select all items that are either failed or abandoned, how do I do that? In general, how do you add an ‘or’ clause in these requests?
