New in: 5.2.2

The prefix operator uses an extended syntax that permits multiple flags to be passed:

[prefix:<flag list>[<operand>]]
  • flag list: a comma delimited list of flags
  • operand: filter operand

The available flags are:

  • casesensitive: (default), this flag forces a case-sensitive match, where upper and lower case letters are considered different
  • caseinsensitive: overrides the default so that upper and lower case letters are considered identical for matching purposes
