Multiple Forms

I’m using two forms for two custom post types. I successfully customized results page for one custom post. Here is my code

<?php
        if (have_posts ()) {

            while (have_posts ()) {

                (the_post());
        ?>
        <?php if($_GET['s']=='uwpsfsearchtrg'){
          //add your own result display here. or you can include the template here as well.
          ?>
          <a class="event-link" href="<?php the_permalink();?>">
          <div class="resource-box">
          <h4><?php the_title(); ?></h4>
          <?php the_excerpt(); ?>
          <ul>
            <li><strong>Eligibility:</strong> <?php echo get_post_meta( get_the_id(), 'eligibility', true); ?></li>
            <li><strong>Phone Number:</strong> <?php echo get_post_meta( get_the_id(), 'phone_number', true); ?></li>
            <li><strong>Coverage Area:</strong> <?php echo get_post_meta( get_the_id(), 'coverage_area', true); ?></li>
            <li><strong>Age Served:</strong> <?php echo get_post_meta( get_the_id(), 'age_served', true); ?></li>
          </ul>
          </div>
        </a>
          <br>
    <?php
    }else{

      ?>

My question is how to filter the search results for the 2nd custom post?
