I would love to be able to search and filter tasks through the API.

For instance, I'd like to search specific Tasks without needing to first fetch all tasks, which takes an eternity with lots of tasks.

Example: We have a naming convention of CUSTOMER | TITLE

Here I'd like to be able to search all CUSTOMER tasks.

I'd also like to be able to filter with relations. We have a task for each customer that is used as a relation in other tasks.

Being able to filter tasks by the ID of a related task would be a huge help. If I do that with the custom_fields filter query, I just get an Internal server error ITEMV2_003

(https://api.clickup.com/api/v2/list/LISTID/task?custom_fields=[{"field_id":"FIELDID","operator":"ANY","value":"TASKID"}])
