Description of problem: To improve usability, the Search text box in the Satellite Web UI requires field help to explain that the asterisk (*) wildcard can be used for partial string searches. For example, the Search field in the Hosts -> Content Hosts page. Additional info: Bug 1275434 was raised to add information about using the '*' to perform searches to the documentation due to queries from customers. Some field-assistance is also required because the searching is not intuitive.
