Query for showing tasks linked to one page

Hey, can someone make me a query, that searches for blocks, that contain a TODO (Tasks) and link to Parkour Project, Parkour Website, Parkour Tool or freePaths
So when I make a task and link this task with Parkour Tool or Parkour Projekt or… then this block should show up in the query. It would be so helpful, if someone has enough time to read and help me. Thanks for all trying to help.

Please check this thread for help on task management.
