Im making (mainly made) a search engine and for a bit more security I want people to only be allowed to search for letters, or numbers (and allow spaces)

How might I co around doing that? I forgot the correct format
somthing like

if ($query eq [a-zA-z] or [0-9))
{

}
else

{
print "Content-type: text/html\n\n";
print "error";
}
would that not allow spaces? because It is a keyword search engine so I need spaces to be allowed also so they can search for more htan 1 keyword.

I think I found out how to include spaces.

So the script would contain somthing like
if ($query eq [a-zA-z] or [0-9) or \s)
{
#nothing happens, the script just keeps going
}
else

{
print "Content-type: text/html\n\n";
print "error";
}
