/*
    Create a new file called search.php and add the following search template. 
    Change the $search_refer= CUSTOM_POST_TYPE to the names of your post types. 
    You will also need to change the template path to the corresponding template you wish to display results.

Add this HTML to the template you wish to display the search form. You will need to change the CUSTOM_POST_TYPE name to the post type you wish to search. You will need to create a new form for each custom post type or use a select menu to set the post_type.
