Case name search bug?

[mlissner]

This query brings back 34 results including ones that mention Collections in the title:

https://www.courtlistener.com/?q=Word%20Collections%20v.%20Pandora&type=r&order_by=score%20desc&case_name=Pandora

But when I copy/paste "Collections" to the case name field, it brings back zero results:

Huh? Is this because we're doing some weird exact matching on the case name, maybe? I wouldn't expect it to do a phrase search in the case name unless I put it in quotes. Is that what's happening, maybe?
