Search module and page limit

Saturday 28 June 2008 9:51:48 am

Hi. I'm working with search module. Looking at the code (kernel/content/search.php) i can see

function pageLimit( $searchPageLimit )
{
    switch ( $searchPageLimit )
    {
        case 1:
            return 5;

        case 2:
        default:
            return 10;

        case 3:
            return 20;

        case 4:
            return 30;

        case 5:
            return 50;
    }
}

So, it seems it's only possible to show search results with page_limit 5, 10, 20, 30 or 50...

but, what about if i need something like 15 or maybe 25? Do i need to hack the core to get this option? Will there be any problems (obviously there we be one if need to upgrade ez core) if i do this little hack?
thank you.
