|`[tag[important]]` |All tiddlers with the tag `important` |
|`[!tag[important]]` |All tiddlers not with the tag `important` |
|`[tag[important]sort[title]]` |All tiddlers with the tag `important` sorted by title |
|`[tag[important]!sort[title]]` |All tiddlers with the tag `important` reverse sorted by title |
|`[[one]] [[two]] [[three]] +[tag[tom]]` |Any of the tiddlers called `one`, `two` or `three` that exist and are tagged with `tom` |
|`[[one]] [[two]] [[three]] [tag[tom]]` |Any of the tiddlers called `one`, `two` or `three` that exist, along with all of the source tiddlers that are tagged with `tom` |
An operator can be negated with by preceding it with `!`, for example `[!tag[Tommy]]` selects the tiddlers that are not tagged with `Tommy`.
The operator defaults to `title` if omitted, so `[[HelloThere]]` is equivalent to `[title[HelloThere]]`. If there are no spaces in the title, then the double square brackets can also be omitted: `HelloThere`.
The operands available with the `is` operator are:
Runs can be preceded with `-` to negate their action, removing the selected tiddlers from the results. For example, `[tag[Tommy]] -HelloThere -[[Another One]]` selects all tiddlers tagged with `Tommy` except those titled `HelloThere` or `Another One`.
Runs can be preceded with `+` in order to make them apply to all of the accumulated results, rather than the original source. For example, `[tag[Jeremy]] [tag[Tommy]] +[sort[title]]` selects the tiddlers tagged `Tommy` or `Jeremy`, and sorts them by the `title` field.
