Testing attribute against list in datomic datalog -


i test in clause in datalog if attribute in particular set (or list). example want test whether :tag-type/code in ["urgent" "todo"] . can this: 

   (or        [?tag-type :tag-type/code "urgent"]        [?tag-type :tag-type/code "todo"]         )

but list parameter. ?tag-names , in lines of : 

       [?tag-type :tag-type/code *in* [?tag-names])]

is possible ?

a friend - without account! - has helped me out. can specify collection in :in-clause : 

[?collection-name  ...]

yielding : 

(d/q '[:find (pull ?tag-type "[*]")        :in $ [?tag-names ...]         :where         [?tag-type :tag-type/code ?tag-names]]          the-db ["urgent" "todo"])
