[Plugin: WP Custom Fields Search] How to force to publish in search.php?

Hello!

I’m still struggling how to force Custom fields search results in to custom search.php page rather than index page.

Hear is explanation:
http://wordpress.org/support/topic/what-conditional-tag-can-i-use-to-identify-the-wp-custom-fields-search-results

But no idea how to implement:
<?php if(function_exists(‘wp_custom_fields_search’))
wp_custom_fields_search(‘my-present’); ?>

with

<form method=”get” id=”searchform” action=”<?php bloginfo(‘home’); ?>/”>
<input type=”text” name=”s” id=”s” value=”Search everything…” onblur=”if(this.value==”) this.value=’Search’;” onfocus=”if(this.value==’Search everything…’) this.value=”;” />
<input type=”hidden” name=”site_section” value=”blog” class=”hidden” />
<button type=”submit” id=”searchsubmit” value=”Search” class=”submit”>Submit</button>
</form>

Desperately looking for answer…please.
