Question

I have a map in Clojure something like this:

(def stuff #{

        {:a "help" :b "goodbye"}
        {:c "help2" :b "goodbye"}
        {:a "steve" :b "goodbye"}
        {:c "hello2" :b "sue"}
    })

: and I want to provide a search so that:

(search stuff "help")

: would return :

 #{
    {:a "help" :b "goodbye"}
    {:c "help2" :b "goodbye"}
}

: What is the simplest way to do this?

Answer 1

user=> (defn search [s q] (select #(some (partial re-find (re-pattern q)) (vals %)) s))
#'user/search
user=> (search stuff "help")
#{{:a "help", :b "goodbye"} {:c "help2", :b "goodbye"}}

This does the trick.
