type Action
  = Update String
  | Enter
  
type alias Model = { text : String }

update : Action -> Model -> Model
update action model
  case action of
    Update txt -> { model | text <- txt }
    Enter ->
      -- probably want to enhance this to add effects
      -- see elm architecture
      -- return an effect to load your data
      { model | text <- "" }

view : Address Action -> Props -> State -> Html
view address props state =
  form
    [ action "javascript:none"
    , onSubmit address Enter
    ]
    [ input
        [ type' "text"
        , placeholder "search"
        , value state.searchTerm
        , on "input" targetValue (Signal.message address << Update)
        ] []
    ]

For future reference, the proper thing to put in there is action "javascript:void(0)". I have no idea if it works for more than one input. I hope so :)
