When trying to search a term that contains the "&" character, using the global search in the ess portal (which uses the search_content.do), returns no results.

Searching for the same term using the global search on the platform (which uses the textsearch.do) finds results.

1. Navigate to Knowledge > Create New.
2. Create a new KB article.
3. In Short Description type AT&T.
4. Save the article.
5. In the global search of the navigation page, search for the term AT&T.
   The article you created appears in the search results.
6. Open the ESS portal.
7. In the global search, search for AT&T.
   Note that the record is not found and the text is cut to AT.

   g_response.sendRedirect(pl + '?sysparm_search=' + g_request.getParameter('sysparm_search'));
   
   to:
