    Creates or adds a property query to an existing file query filter.

    When you wire this function to Query Files, the results contain only files that have property attributes that satisfy the query entry. If you specify multiple property queries for the same property, only files that match all queries open.

    connector_pane_image
    datatype_icon

    operator

    Criteria for how to filter files on the server.

    Default: contains

    datatype_icon

    filter in

    Query or queries you want to use find matching files on the server.

    Default: new filter

    datatype_icon

    key

    Unique identifier for the property you want to locate.

    datatype_icon

    value

    Metadata property to add.

    datatype_icon

    error in

    Error conditions that occur before this node runs.

    The node responds to this input according to standard error behavior.

    Standard Error Behavior

    Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

    error in does not contain an error error in contains an error
    If no error occurred before the node runs, the node begins execution normally.

    If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

    		If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

    Default: No error

    datatype_icon

    filter out

    Updated query or queries to find matching files on the server.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.
