What exactly is a "nested filter"?

[Michael Gold]

I have Googled this question, but it doesn't really give me a well-defined answer. Could someone help me with this question and provide an example for me please. Thank you so much for your help and support.

Hello @Michael Gold 

A nested filter example could be using one saved filter within another thus:

project = myProject and issue in (filter=12345)

"12345" is the numeric ID assigned to a particular saved filter. This example says to retrieve issues that are in project "myProject" and that also meet the criteria specified in the saved filter with ID 12345.

Do you have a particular filtering scenario you are trying to build?

[Michael Gold]

No mam, I don't have a particular filtering scenario. I am currently learning and preparing for my ACP-120 exam. 

Okay, so the nested filter is (filter=12345)?

[Trudy Claspill]

yes, that's correct.

Hi @Michael Gold , a nested filter is a reference to a saved filter within JQL.

An example:

Search the results of the filter "My Saved Filter" (which has an ID of 12000) for issues assigned to the user jsmith:
filter = "My Saved Filter" and assignee = jsmith
or
filter = 12000 and assignee = jsmith

Okay, so "12000" is the nested filter that references "My Saved Filter"?
