Dataview plugin snippet showcase

So, I’m having sooo much trouble with contains, can somebody help please…
in my notes I have…
## Metadata Authors:: [[Justin Erik Halldór Smith]] ItemType:: [[Blog post]]
and I’m tring to get a dataview of those blog posts, or websites, or magazines, etc. I have this dataview
TABLE Title, ItemType, Date from "Zotero mdNotes" WHERE ItemType SORT desc
which gives me this…


But I cannot for the life of me (been at it all day today) get it to produce a table of just the blog posts.

Any ideas?
