Thread: GUI user input error message

I need help implementing the below code. It currently is the code for a search bar. User enters in keywords and then it matches it against the recipe, returning true if so. It then displays the recipes matching in the interface. However, I want to implement an error message for invalid input. Currently with the below code it just brings up the error regardless, I added a break, but then it removed all the content from the interface. else if(recipe.foundWords(keys)) =! true) //do stuff ? is another option I tried.
Obviously not the result I'm wanting.

            for(CakeRecipe recipe : recipeSet.getAllCakeRecipes()) 
            {
                if(recipe.foundWords(keys)) 
                {
                    searchRecipe.add(recipe);
                }
                else
                {
                    JOptionPane.showMessageDialog(this,"No recipe containing search words found.", "Error!",
                                                    JOptionPane.ERROR_MESSAGE);
                }
 
            }

Suggestions?

The code runs and what not. However, right or a wrong keyword match still displays the error message. If wrong, it iterates 10 times (10 recipes in the array list) and then brings up a blank interface without showing any recipes. If it is right - the match, it iterates 10 times and then displays the correct recipe.

I need to break from the iteration, somehow. The break only stops the iteration, BUT invalid input = no recipes on the interface (which should still have all the recipes) and if it's correct input = no recipe match cos it obviously breaks where it isn't receiving the code to display the recipes.

/**
     * Searches the cakes using the search string
     * @param searchString
     * list of keywords to be searched in a cake recipe
     */
    private void searchAll(String searchString) 
    {
        if(searchString.isEmpty())
        {
            createCenterPanel();
        }
        else 
        {
            ArrayList<CakeRecipe> searchRecipe = new ArrayList<>();
            centerPanel.removeAll();
            String[] keys = searchString.split(" ");
 
            for(CakeRecipe recipe : recipeSet.getAllCakeRecipes()) 
            {
                if(recipe.foundWords(keys) != true) 
                {
                    JOptionPane.showMessageDialog(this,"No recipe containing search words found.", "Error!",
                                                    JOptionPane.ERROR_MESSAGE);
 
                }
                else
                {
                   searchRecipe.add(recipe); 
                }
                break;
            }
            Collections.sort(searchRecipe);
