Is it possible to use wildcards in queries?

Since you said start with, one way to do this below. You can replace starts-with with includes or ends-with.

#+BEGIN_QUERY
{:query [:find (pull ?b [*])
         :in $ ?s
         :where
         [?b :block/original-name ?n]
         [(clojure.string/starts-with? ?n ?s)]]
 :inputs [ "task.myName." ]
 }
#+END_QUERY

If you want to use wildcards, you need to use regex, check out Bailey Jennings’ search query here. If you need further assistance, just tell.
