Hi to all, it may well be, that this question has been answered elsewhere (which I did not notice). I am having trouble to build a query that does the following: Search for blocks which contains a page name like [[@MN]] (for My Name) AND contains the tag #talk AND is an item with status TODO So …

And is always used between statements. However your query does not link ?b and ?t currently. So you will need a [?b :block/refs ?t] statement after [?t :block/name "talk"].
