Inconsistent suggestions for Fields between Basic and Advanced searches

Problem definition

• In Basic search, it's possible to get a complete list of fields suggested with just part of the field name.
  • For example, searching with word date: all fields with the word date in the name will be suggested.
    
• In Advanced search, only fields with the beginning of the name matches the search string will be suggested.
  • ** For example, searching with word date: only fields with field name starts with date will be suggested.
