Wrong results when {host.name} includes a minus (-) character

[Matthias]

Expected Behavior

If the host name contains a minus (-) character I only receive results for this host when querying elasticsearch like this:
fields.host_name={host.name}
hostname: `demo-host.local'

Current Behavior

I receive results for all fields.host_name containing demo or host.local

Possible Solution

Wrap the {host.name} in double quotes when translating to elasticsearch query

Steps to Reproduce (for bugs)

Compare the results of the lucene queries
fields.host_name:demo-host.local
and
fields.host_name:"demo-host.local"

Your Environment

You'll want to change your mapping type on your index to "keyword" for the hostname, or try using the .keyword type in your query. - eg fields.host_name.keyword={host.name}
