type: text/vnd.tiddlywiki
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]]` |
