Searching under an item with a tag

[Bjarke_Ebert]

I think this is useful not only for tags, but also normal search term.
Here is my similar suggestion

Find search terms in parent nodes as well

Maybe my example is a bit too abstract. A better example could be a search for [ #TODO vacation ] which would find + Vacation plan + + ... + + ... + + book hotel #TODO or searching for [schweiz tax] would find + My schweiz notes + + ... + + tax <--- find this + + My Denmark notes + + tax <-- not this
