While looking for a solution to this problem, I read this post.
Now I found the solution I will write it below.
Also in my situation it war required to work on other language.

<script>
  function avalcm_search_link(vas){
    var link1=document.getElementById("home_url").value;
    var sublink=document.getElementById("categ_base_lang").value;
    var link2="";
    if (vas!="") {
      var link2=sublink + "/" + vas + "/";
    }
    var link=link1+link2;
    document.getElementById('searchform_special').action = link;
  }
</script>

<form role="search" method="get" id="searchform_special" action="<?php echo esc_url( home_url( '/'  ) ); ?>">
  <div>
    <label class="screen-reader-text" for="s"><?php _e( 'Search for:', 'woocommerce' ); ?></label>
    <input type="text" value="<?php echo get_search_query(); ?>" name="s" id="s" placeholder="<?php _e( 'Search for products', 'woocommerce' ); ?>" />
    <select onchange="avalcm_search_link(this.value)" >
       <option value=''>All</option>
   <?php
    $sql="SELECT taxonomy,slug, <code>name</code> from wp_term_taxonomy , wp_terms where wp_term_taxonomy.term_id=wp_terms.term_id and taxonomy in ('product_cat','') ORDER BY taxonomy ASC , term_taxonomy_id asc;";
    $allfilters = $wpdb->get_results($sql);
    foreach ($allfilters as $singlefilter) {
      echo '<option value="'. $singlefilter->slug.'">' . $singlefilter->name. '</option>';
    }
   ?>
   </select>
   <input type="submit" id="searchsubmit" value="<?php echo esc_attr__( 'Search' ); ?>" />
   <input type="hidden" name="post_type" value="product" />
   <input type="hidden" id="home_url" value="<?php echo esc_url( home_url( '/'  ) ); ?>" />
   <input type="hidden" id="categ_base_lang" value="<?php echo _x('product-category', 'slug', 'woocommerce') ?>" />
  </div>
</form>

So i change the action value of the form every time that i change value in select .

I hope this will help someone
