 The plugin creates modified copies of a few field types to make the YAML based content from Kirby ready for queries.
 You can use
 
 - `fieldname[]` to query for a value in an array from pages/files/user fields and
+- `fieldname{}` to query for an objectId in an array from pages/files/user fields and
 - `fieldname[,]` to query for fields in comma separated strings like tags/select/radio/checkbox/multiselect fields.
