| subCaseInstanceId | Restrict query to one process instance that has a sub case instance with the given id. |
| caseInstanceId | Restrict query to all process instances that are sub process instances of the given case instance. Takes a case instance id. |
| processDefinitionId | Filter by the process definition the instances run on. |
| processDefinitionKey | Filter by the key of the process definition the instances run on. |
| processDefinitionKeyNotIn | Exclude instances that belong to a set of process definitions. Must be a comma-separated list of process definition keys. |
| processDefinitionName | Filter by the name of the process definition the instances run on. |

| incidentMessage | Filter by the incident message. Exact match. |
| incidentMessageLike | Filter by the incident message that the parameter is a substring of. |
| startedBy | Only include process instances that were started by the given user. |
| startedBefore | Restrict to instances that were started before the given date. The date must have the format yyyy-MM-dd'T'HH:mm:ss, e.g., 2013-01-23T14:42:45. |

| variables | Only include process instances that have/had 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.
key is the variable name, operator is the comparison operator to be used and value the variable value.Note: Values are always treated as String objects 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.key and value may not contain underscore or comma characters.
