 There is a GraphQL PLayground for testing queries at http://localhost:8080/ .
 
+Example Query:
+```
+query($filter: JobFilterList!, $sorting: OrderByInput!, $paging: PageRequest!) {
+  jobs(
+    filter: $filter
+    order: $sorting
+    page: $paging
+  ) {
+    count
+    items {
+      id
+      jobId
+      userId
+      startTime
+      duration
+    }
+  }
+}
+```
+
+Using the Query variables:
+```
+{
+  "filter": { "list": [
+    {"userId": {"contains": "unrz"}},
+    {"duration": {"from": 60, "to": 1000}},
+    {"startTime": {"from": "2019-06-01T00:00:00.00Z", "to": "2019-10-01T00:00:00.00Z"}}]},
