Description of problem:

If a customer creates a custom Host Parameter (we'll call it "myparameter") for a number of Hosts, they can search on that parameter in the hosts search field with the following search and get the list of hosts that have it set:

   "has params.myparameter"

However, if they invert the search with the following, they get no hosts results returned.

   "not has params.myparameter"

This is not the situation with other searchable criteria (e.g. "has hostgroup" vs. "not has hostgroup").   This appears to only be related to searching for parameters (params).   This appears the same whether searching via API or via WebUI


Version-Release number of selected component (if applicable):

  Satellite 6.2.12
  Also appears to be the same in Satellite 6.3 Beta

How reproducible:
Steps to Reproduce:
1.  Create a host parameter 
  under "Hosts", specific host, "Edit", Parameters tab, add parameter "myparameter" with some value.

2.  Search on hosts that do not have that parameter set.

Actual results:

   Under hosts, search for "has params.myparameter" and the hosts with the parameter will be returned in the result set.

   Invert the search with "not has params.myparameter" and the returned result set will be empty.


Expected results:

   The inverted "not has params.myparameter" should return all the hosts that do not have that parameter set.
