The ''prefix'' filter operator returns the titles in the current list that start with a specified prefix. If the ''prefix'' operator is preceded by `!` then it returns the titles that do not start with the specified prefix.

For example:

|!Filter String |!Description |
|`[tag[task]!prefix[hidden]]` |Returns tiddlers tagged `task` whose titles do not start with `hidden` |
|`[prefix[$:/]]` |Equivalent to `[is[system]]` |
