Hi guys!

Just adding a note to connect things better.

Thanks!

I believe the _ was left off accidentally before - I'm not familiar with this syntax without an underscore, and I searched the codebase and found NO other references like this (git grep '\.\. ' | grep -v 'code-block' | grep -v 'note' | grep -v 'section' | grep -v '\.\. _' | grep -v 'configuration-block' | grep -v versionadded | grep -v 'warning' | grep -v '//' | grep -v '\-\->' | grep -v 'include' | grep -v 'caution' | less gets you a short list, where you can see this). Also, this section header already gave us a #filtering-collections anchor, even without the added reference.
