Unable to use logical operator (OR) on lambda whereFilter

Hi there,

I've a working deadman alert generated through the wizard, but when I add another server to the alert it stop working.

Working
...
var whereFilter = lambda: ("host" == 'dev-mongodb-n1' )
...
Not Working
...
var whereFilter = lambda: ("host" == 'dev-mongodb-n1' OR "host" == 'dev-mongodb-n2')
...

Is it possible to use wildcards instead ?

Thanks in advance!

**Full Code**
var db = 'telegraf'

var rp = 'autogen'

var measurement = 'procstat'

var groupBy = []

var whereFilter = lambda: ("host" == 'dev-mongodb-slave-2')

var period = 1m

var name = 'mongod-process-is-not-running'

var idVar = name

var message = 'TEST! DEV {{.Level}}: {{.ID}} from {{.Time}}'

var idTag = 'alertID'

var levelTag = 'level'

var messageField = 'message'

var durationField = 'duration'

var outputDB = 'chronograf'

var outputRP = 'autogen'

var outputMeasurement = 'alerts'

var triggerType = 'deadman'

var threshold = 0.0

var data = stream
|from()
.database(db)
.retentionPolicy(rp)
.measurement(measurement)
.groupBy(groupBy)
.where(whereFilter)

var trigger = data
|deadman(threshold, period)
.stateChangesOnly()
.message(message)
.id(idVar)
.idTag(idTag)
.levelTag(levelTag)
.messageField(messageField)
.durationField(durationField)
.opsGenie2()
.teams()
.recipients()

trigger
|eval(lambda: "emitted")
.as('value')
.keep('value', messageField, durationField)
|eval(lambda: float("value"))
.as('value')
.keep()
|influxDBOut()
.create()
.database(outputDB)
.retentionPolicy(outputRP)
.measurement(outputMeasurement)
.tag('alertName', name)
.tag('triggerType', triggerType)

trigger
|httpOut('output')

Start with the whereFilter lambda in the full TICKscript and reproduce the difference between the single-host predicate and the predicate using OR. Trace how the deadman alert handles the multi-host filter; done means the intended host selection works reliably, with the supported wildcard behavior clarified if applicable.
