questions regarding the resulting query_string:
do the overlapping and/or touching matches have to be in the same order in which they are indicated in the @query array. That is, given:

my $string ="EICHENBAUMSCHULE";
my @query = qw(EIC BAUM UMS CHU LE);
[download]

would the following also match

<BR>
BAUMSLECHU  # the CHU and LE are not in the same order as indicated in
+ @query
[download]
