Improve search in users and groups

The current search functionality can be described as follows:

• Doesn’t search across all relevant database properties, e.g. ‘’Group’’
• Search is sometimes partial and sometimes non-partial; it depends on the database property (it is inconsistent)
• For some database properties search is case-sensitive, for others it is not, e.g. it is case-sensitive for ‘’Username’’ but not for ‘’First name’’
• There is no way to return to the original list (non search-results list) without clearing the search field and executing a search; this is not user friendly

CHANGES REQUIRED

The new search functionality uses the following mechanisms across 'users', 'groups' and 'edit group members':

• it is not case sensitive (across any property included in the search)
• it does not require an exact match; partial returns results where available (across any property included in the search)
• it searches across all characters: numbers, letters and otherwise (e.g. @) (for all properties included in the search)
• within ‘’Users’’ it searches across the following 2 additional properties:
  • group
  • type

The search bar utilises the following interaction behaviour:

• Pressing enter or clicking on the magnifying glass executes the search; the magnifying glass changes to an ‘’X’’, focus on the field is removed and the list updates with correct results
• Placing focus on the field clears the placeholder text, or the previously-entered search term, and the magnifying glass is displayed
• A user can exit and clear the search by doing any of the following:

• • Clicking the ‘’X’’ (magnifying glass, placeholder text and normal list are displayed)
