Question

I want to replace space characters with plus signs in the search query I send to google.

(defn search-google [search-term]
  (clojure.string/replace search-term #" " "+")
    (browse-url 
      (str "http://google.ca/search?q=" search-term)))

However my function fails as my search-term retains spaces.

(search-google "clojure user input")

URISyntaxException Illegal character in query at index 32:
http://google.ca/search?q=clojure user input  java.net.URI$Parser.fail (:-1)

I am new at clojure and suspect I am missing something obvious.

A new fixed search-term is being created, then the fixed one is ignored and the unchanged one is passed to browse-url:

(def browse-url println)                                                                                                                                                  
(defn search-google [search-term]                                                                                                                                         
  (let [fixed-search-term (clojure.string/replace search-term #" " "+")]                                                                                                  
    (browse-url                                                                                                                                                           
     (str "http://google.ca/search?q=" fixed-search-term))))  

user> (search-google "a b c")                                                                                                                                             
http://google.ca/search?q=a+b+c                                                                                                                                           
nil
