Description of problem:
If user uses scoped-search reserved words (such as operators, parentheses, =, etc.) as entity attribute values (name, description, etc), auto_complete suggests using it unquoted which results in wrong query:
e.g. with organization name = AND:
'name = AND' instead of 'name = "AND"'

- applies to both Foreman and Katello pages.

How reproducible:
always

Steps to Reproduce:
1. create instance of any entity (e.g. Architecture) with a reserved word as a name (e.g. "(")
2. navigate to Hosts > Architectures
3. focus the search bar
4. click the search suggestions: name -> name = -> name = ( -> name = (( -> ...
5. click search

Actual results:
no or funky results

Expected results:
such values should appear double-quoted in the suggestion exactly as multi word values:
name = "(" -> 1 result
