in reply to Split question...

What is the best way to split each keyword?

The docs on split (in perlfunc) mention a special-case for dealing with multiple spaces.

When you do 

  ($key1,$search_keys) = split / /, $search_keys, 2;

is it your plan to do this in a loop, pulling of next search term each time through? I would think it would be easier to just do 
  @keys = split / /, $search_keys;

Or is there something about item numbers that makes it easier to do it your way?

    Well, here is how I'm doing it....
    $search_keys = $in{keywords};
while ($search_keys) {
    ($key1,$search_keys) = split /\s/, $search_keys, 2;
    if (Check_Database($key1)) { # checks if item num
$page_content .= Get_Search_Results($key1,"item_num");
    } else {
$search_engine .= Get_Search_Results($key1,"keyword");
    }
}

    That is not working though. I don't know why, I guess I'll just play with it, while taking Mad Hatters advice of /\s+/ in the split, just in case they put more spaces then 1.

    Thank you for your advice.

    thx,
    Richard

      Wouldn't it be easier to do something like 
      @search_keys = split /\s+/, $in{keywords};
foreach $key (@search_keys) {
    if (Check_Database($key)) { # checks if item num
        $page_content .= Get_Search_Results($key,"item_num");
    } else {
        $search_engine .= Get_Search_Results($key,"keyword");
    }
}
