Multi-value properties and queries

I want the ability to have a property which has several values. For example, in my videos, I want a topic property which might look like

topic:: logseq, queries

there seem to be several issues with this that I’m unable to resolve. First, it appears that logseq views the above as a property with a single value “logseq, queries” instead of “logseq” and “queries”. Second, if I don’t include double quotes around the values, it tries to create pages called “logseq” and “queries”. I don’t want the extra pages and i want “topic” to be treated as it as 2 properties so that if I query (property topic logseq), I get a hit. This seems like it should be straight forward. What am I missing?
