 if(isset($params['sCity'])) {
        if(osc_list_city_id()==$params['sCity']) {
          $url .= osc_sanitizeString(osc_list_city_slug()) . '-c' . osc_list_city_id();

        } else {

          } else {

Doable but not recommended unless you know what you're doing and have decided to maintain a separate codebase as you'll be modifying several files and changing search logic.

Hint: start by searching for all instances of '-c' which will give you an idea of the effort involved.

Only "-c" in 2 files

1. oc-includes\osclass\helpers\hSearch.php

if(isset($params['sCity'])) {
        if(osc_list_city_id()==$params['sCity']) {
          $url .= osc_sanitizeString(osc_list_city_slug()) . '-c' . osc_list_city_id();

        } else {
          if(is_numeric($params['sCity'])) {
            $city = City::newInstance()->findByPrimaryKey($params['sCity']);
          } else {
            $city = City::newInstance()->findBySlug($params['sCity']);

            if(!isset($city['pk_i_id'])) {  // update 440
              $city = City::newInstance()->findByName($params['sCity']);
            }
          }

          if(isset($city['s_slug'])) {
            $url .= osc_sanitizeString($city['s_slug'] != '' ? $city['s_slug'] : $city['s_name']) . '-c' . $city['pk_i_id'];
          } else {
            // Search by a city which does not exists (by form)
            // TODO CHANGE TO NEW ROUTES!!
            // return $url . 'index.php?page=search&sCity=' . urlencode($params['sCity']);

            // Lang code in base URL cannot be used
            return osc_base_url(false, false) . 'index.php?page=search&sCity=' . urlencode($params['sCity']);
          }
        }
      }

        $search_uri = preg_replace('|.*?/|', '', $search_uri);
        if(preg_match('|-r([0-9]+)$|', $search_uri, $r)) {
          $region = Region::newInstance()->findByPrimaryKey($r[1]);
          if(!$region) {
            $this->do404();
          }

          Params::setParam('sRegion', $region['pk_i_id']);

          if(osc_subdomain_type() != 'category') {
            Params::unsetParam('sCategory');
          }

          if(preg_match('|(.*?)_.*?-r[0-9]+|', $search_uri, $match)) {

I'm removed "-c" URL get expected but 404 Error

because now your URL is considered as "category url" because it match category pattern.

because now your URL is considered as "category url" because it match category pattern.

Any Solution ??

We plan to enhance search patterns and urls in future in way like this:
/some/text - category url
/a/sometext - city url
/b/sometext - region url
/c/sometext - country url
/d/some/text - region + city url
/e/some/cool/text - category + region + city

etc.
Means there is one letter (a,b,c...) that is not anyhow bad for SEO and you still able to create various patterns
You might test something like this.

Not simple....
