useHistory = Auto | None | True | False
* useHistory defines the savedSearch module's saved search dispatch method. The default useHistory method is None, which means that savedSearch first tries to find a previously run job if one exists in the saved search's history. If it can't find a previously run job, savedSearch dispatches a new job based on the saved search and returns that job's sid. If useHistory is set to True, savedSearch looks only for previously run jobs dispatched by the saved search. If useHistory is set to False, savedSearch dispatches a new job based on the saved search and returns that job's sid, regardless of the presence of jobs within the saved search's history.
* defaults to: Auto
Keep in mind that keeping this value at False over time may lengthen the load time of your panel.
