Auto-search on status selection

[blootsvoets]

Right now, on selecting a status to search on, the user first has to press search to actually enable this selection. To me it would be more intuitive to immediately search when a new status is selected, without having the additional button. Likewise, for the participant box, a debounce could be used to search once the user has stopped typing for a short while (e.g., 0.5 seconds).
