                                                  int limit)

  Description copied from interface: `InstanceManagement`

  Retrieve and returns information about all, or some process instances. The request identifies the process instances using a filter that can select instances with a given name, status, property values, etc. Without a filter, the operation returns all process instances up to a specified `limit<.code>. The request also indicates which key fields to use for ordering the results.`

  The filter element can be used to narrow down the list of process definitions by applying selection criteria. There are six filters that can be applied:

  - name -- Only process instances with this local name.

  - namespace -- Only process instances with this namespace URI.

  - status -- Only process instances with these status code(s).

  - started -- Only process instances started relative to this date/time.

  - last-active -- Only process instances last active relative to this date/time.

  - $property -- Only process instances with a correlation property equal to the specified value.

  The name and namespace filters can do full or partial name matching. Partial matching occurs if either filter ends with an asterisk (*). These filters are not case sensitive, for example name=my* will match MyProcess and my-process. If unspecified, the default filter is name=* namespace=*.

  The status filter can be used to filter all process definitions based on six status codes:

  - active -- All currently active process instances (excludes instances in any other state).

  - suspended -- All process instances that have not completed, but are currently suspended.

  - error -- All process instances that have not completed, but are currently indicate an error condition.

  - completed -- All successfully completed process instances (excludes instances in any other state).

  - terminated -- All process instances that were terminated.

  - faulted -- All process instances that encountered a fault (in the global scope).

  The started filter can be used to filter all process instances started on or after a particular date or date/time instant. The value of this filter is either an ISO-8601 date or ISO-8601 date/time. For example, to find all process instances started on or after September 1, 2005, use started>=20050901. Similarly, the last-active filter can be used to filter all process instances based on their last active time. The last active time records when the process last completed performing work, and either completed or is now waiting to receive a message, a timeout or some other event.

  Each process instance has one or more properties that are set its instantiation, that can be used to distinguish it from other process instances. In this version of the specification, we only support properties instantiated as part of correlation sets defined in the global scope of the process. For example, if a process instantiates a correlation set that uses the property order-id, it is possible to filter that process instance based on the value of that property.

  The property name is identified by the prefix $. If the property name is an NCName, the filter will match all properties with that local name. If the property name is {namespace}local, the filter will match all properties with the specified namespace URI and local name. For example, to retrieve a list of all active process instances with a property order-id that has the value 456, use status=active $order-id=456.

  By default the response returns process instances in no particular order. The order element can be used to order the results by specifying a space-separated list of keys. Each key can be prefixed with a plus sign '+' to specify ascending order, or a '-' minus sign to specify descending order. Without a sign the default behavior is to return process instances in ascending order. The currently supported odering keys are:

  - pid

  -- Order based on the process identifier.

  - name

  -- Order based on the local name of the process instance.

  - namespace

  -- Order based on the namespace URI of the process instance.

  - version

  -- Order based on the version number.

  - status

  -- Order based on the status of the process instance.

  - started

  -- Order based on the process instance start date/time.

  - last-active

  -- Order based on the process instance last active date/time.
