Adjusting GROQ query to filter out current document based on tags.

Still learning how to write more advanced custom GROQ queries and I'm using this to return all related documents based on tags:
(as found here:
https://www.sanity.io/schemas/get-related-items-of-a-post-in-sanity-by-comparing-category-array-reference-with-another-array-0d752dd7 )
However, this returns the current document again, as it's got the same tags. How can I adjust this to filter out the current document? (something like

slug.current != slug

but this doesn't take into consideration what the ^ and @ operators do (still learning this).

The caret (

^

) is the parent operator, which means it goes one level up in scope. A filter boils down to one or more booleans, returning every document that matches them all. By adding an additional check to your “related” filter that ensures the document doesn’t match the parent, you can avoid returning the current document again. Something like

_id != ^._id

should work.

Here,

_id

is in the context of the “related” filter, while

^._id

is in the context of the parent (not shown in the original post, but implied to exist).

This is perfect. Brilliant explanation. I've used the

^

operator once, but not fully grasped it. This is great. Thanks!
