I am planning in adding a new method processInstanceBusinessKeyLike(String businessKeyLike) to the HistoricProcessInstanceQuery API and implementations because I have a need for it.
I would like to know if a pull request with this feature would be accepted or if there is a specific reason why this is not desirable.
I remark there is already a similar method in the TaskInfoQuery API for retrieving tasks where the process business key is like a given a string.
Thank you @filiphr. I went ahead and implemented the feature, including adding support to ProcessInstanceQuery as well, as you suggested. I also added support to the corresponding REST api queries via the new parameter businessKeyLike The pull request is at https://github.com/flowable/flowable-engine/pull/2033
