With Filter Deployer on a filtered search there is a new icon on the search filter name next to the close icon.
To share follow these steps:
1 - Click Share Icon
2 - Select Users
3 - And that's it!
By default all users can create Filter Templates but they can be limited to Admin users and accessed from the admin panel
To use the Filter Templates follow these steps:
1 - Click the Add Filters to Template action menu item or the plus on the Filters Subpanel
2 - Select the filter from the appropriate user using the drop downs
3 - Once all of the filters are added click the Deploy Template action item
4 - Choose to deploy to Users, Roles, or Teams
5 - Select deploy objects
6 - Deploy
If the original filters are changed just redeploy them and Filter Deployer will update the deployed to user's filter if it was copied from another user
