hmm, i have not tested, but i think this should work:

open search.php

goto line 451

shold look so:

PHP Code:

if (trim($query)=="" and $DB_site->num_rows($users)==0) { 


change it so:

PHP Code:

if (trim($query)=="") { 


after

PHP Code:

$userssql=" AND (1=0 ";
    while ($user=$DB_site->fetch_array($users)) {
      $userssql.=" OR post.userid='$user[userid]'";
    }
    $userssql.=")"; 


add this:

PHP Code:

if($DB_site->num_rows($users)==0 {
$userssql=" AND post.postusername='$searchuser' ";  

} 


hope this could help

it finds only the exact usernames i think, but you can surely optimize it ^^
