| superCaseInstance | Restrict query to all process instances that are sub process instances of the given case instance. Takes a case instance id. | 
| subCaseInstance | Restrict query to all process instances that have the given case instance as a sub case instance. Takes a case instance id. | 
| active | Only include active process instances. Value may only be true, asfalseis the default behavior. | 
| suspended | Only include suspended process instances. Value may only be true, asfalseis the default behavior. |

| withoutTenantId | Only include process instances which belong to no tenant. Value may only be true, asfalseis the default behavior. | 
| activityIdIn | Filter by a comma-separated list of activity ids. A process instance must currently wait in a leaf activity with one of the given activity ids. | 
| rootProcessInstances | Restrict the query to all process instances that are top level process instances. | 
| processDefinitionWithoutTenantId | Only include process instances which process definition has no tenant id. | 
| variables | Only include process instances that have variables with certain values.
    Variable filtering expressions are comma-separated and are structured as follows: A valid parameter value has the form key_operator_value.keyis the variable name,operatoris the comparison operator to be used andvaluethe variable value.Note: Values are always treated as Stringobjects on server side.Valid operator values are: eq- equal to;neq- not equal to;gt- greater than;gteq- greater than or equal to;lt- lower than;lteq- lower than or equal to;like.keyandvaluemay not contain underscore or comma characters. | 
Result
A JSON object that contains the count as the only property.
| Name | Type | Description | 
|---|---|---|
| count | Number | The number of matching process instances. |
