I have 5 custom post types in my website and i need to make a search form for each one to show only results from it. What should be in the search form to only show results from the custom post type which it came from? How do i redirect from each page to a specific page results?
<form role="search" method="get" action="/">
<input type="hidden" id="cat" name="paints_buildings" />
<input type="text" size="16" name="s" placeholder="Search" />
<input type="submit" value="Go" />
</form>
