Yes, if I search it can find the text in the note. What I was trying to do is an intelligent search. For example, the way you can search tag:test you could search, in your example, crazy-tag:value along with other search parameters. Similar to the way you can with an embedded DataView query. It seems however that Obsidian doesn’t allow custom yaml fields to be used as search parameters other than searching by text just as it would any other text.
