If I run a search that says * host=*somehost*, I get results back. If I remove the wildcards around the host field and only run index=blah host=somehost, then nothing is returned.
The host field is just "somehost" (without quotes). If I go to the selected fields sidebar and select "somehost" out of the values of host, it generates the search * host=*somehost* host="somehost" and returns no results. Same if I select the "somehost" value out of an event returned from the wildcard search and generate a new search from that.
What would cause Splunk to require that there are wildcards around this hostname?
