The UI contains an option to filter by any column
So for example, if the user the string "ab" in the filter it will show also workflfow runs with status aborted, and also workflow runs with id containing "ab"
Currently this feature is implemented in the UI, but being that we are moving to use pagination the API /v2/workflows/instances must support this.

Refer to SonataFlow doc to see which operators are available for each attribute type.
