Search Functionality

Hi Experts,

I need to build a Search Functionality in Camunda Standard Tasklist which will allow me to search all the variables which reside within the Database. My challenge is

  1. What approach should I task.
  2. Can I use a Plugin to put this custom piece in Tasklist navbar
  3. Do we have any sample on the Tasklist plugins
    4.If I try to use a Filter for all such searches, how can I provide a filter search for all non admin users who have restricted access to there there tasks only. Basically the non admin user should be able to do a search on all the records within the Database for view purpouse only

Any guidance will be of great help. Thanks

Regards
Gaga
