Trying to create a "Seaweed" filter

[tracc]

I apologise if this belongs somewhere else, I’ve searched through the forums and not found my answer.

I’m trying to save myself a broad search term for algae which I could then use with a map circle to zoom in on “seaweed near me”. I thought I understood how to do this by appending all the taxa codes.

Chlorophyta: taxon_id=50863
Rhodophyta: taxon_id=57774
Ochrophyta: taxon_id=48221

When I string them together;
https://www.inaturalist.org/observations?taxon_id=50863,57774,48221

I get a totally blank page.

What am I doing wrong please?

it needs to be taxon_ids plural when you string together multiple taxa

Thank you @thebeachcomber !
