A query transclusion is specified by the following sequence, starting at the first position in a line: `{{{query:query-expression}}}`.
The line must literally start with the sequence `{{{query:`.
Everything after this prefix is interpreted as a [query expression](00001007700000).

When evaluated, the query expression is evaluated, often resulting in a list of [links](00001007040310) to zettel, matching the query expression.
The result replaces the query transclusion element.

For example, to include the list of all zettel with the [tags](00001006020000#tags) “#search”, ordered by title specify the following query transclude element:

    {{{query:tags:#search ORDER title}}}

This will result in:



For example, this allows to create a dynamic list of zettel inside a zettel, maybe to provide some introductory text followed by a list of child zettel.

The query will deliver only those zettel, which the current user is allowed to read.

In the above example, the action list is empty.
This leads to the described list of zettel.

The following actions are supported, parameter and aggregate actions:



To allow some kind of backward compatibility, an action written in uppercase letters that leads to an empty result list, will be ignored.
In this case the list of selected zettel is returned.

Example:

    {{{query:tags:#search | tags}}}

This is a tag cloud of all tags that are used together with the tag #search:
