How to search for label with a space?

I have a label “High Quality” that I apply to some articles. When I try to do a search, it seems that I can’t search for this label, as described on the following page:
https://tt-rss.org/wiki/SearchSyntax

Both of the following searches yield no results:
label:High Quality
label:“High Quality”

I didn’t really expect the first to work, but I was expecting quotes to work. Is this a bug? I suppose my workaround could be to use the label “High_Quality” instead, but I was just curious.

If it matters, I am attempting to use the vf_search plugin to make a feed of something like:
label:High Quality -label:Right Bias

Thanks!

The quotation marks version should now work (as of commit f2f2b6d1f4). Prior to that you’d need to use a single word.

Thanks! I’ll update and try it out
