He said R, not r, here is quick example of what he meant
alias testR {
tokenize 32 this is the test sentence : plop.
hadd -m badword .*test.*
hadd badword plop
hadd badword .*is\sthe.*
echo -a > $hfind(badword,$1-,0,R)
hfree badword
}
In regex, \s is a space and .* is used to represent the * wildcard (in order to have an item name where spaces can exists).
Then, mirc compare (using regex) each item (that represent regex pattern) with $1- (like if ($regex($1-,itemN)) { })
