UdmSearch: Re: Creation of a new feature of Mnogo PHP Search facility.

[Laurent LEVIER]

Ok, I will change my query with the first one.

After a test, yes it slows the display of the page. So I changed a bit my howto.

I removed the init.inc changes and put into template.inc after the 
lang_url_translation treatment:

    // ----------------------------------------------------------------------
    // Laurent LEVIER changes to add NU code to return number of indexed URLs
    // ----------------------------------------------------------------------
    if (ereg('\$NU',$str))
    {
       $query ="SELECT count(*) FROM url WHERE status IN (200,304)";

       if($DEBUG) echo "last_parse(): ",$query,"<BR><HR>";

       if (!$res=db_query($query)) print_error_local('Query error: '.$query."\n<
BR>".db_error());

       $numurlsdb="10";
       if ($row=db_fetchrow($res))
       { $numurlsdb=$row[0]; }

       db_freeresult($res);

       $str=ereg_replace('\$NU', $numurlsdb, $str);
    }

    // ----------------------------------------------------------------------
    // Laurent LEVIER changes to add NU code to return number of indexed URLs
    // ----------------------------------------------------------------------

Works also fine, and have the advantage to be included easily. Only activated when you 
request the feature :)
