Multiple Filters

Hi,

I am building a trade blotter, a GUI that displays trades taken from a MySQL
database, with one trade per row, including information such as date,
amount, currency, etc.  I would like to be able to filter by multiple
criteria.  I am using glazed lists and have sorting and single filtering
working.  I implement a class that extends AbstractMatcherEditor and use
another class that implements Matcher to do the filtering decisions.  I'm
just not sure how to do multiple filtering, where I filter first by amount,
per se, and then by date, to be left with only a particular amount on a
particular date.  Currently doing this would cause filtering by amount and
then filtering by date, basically losing the amount information.  Any help
is greatly appreciated.  Thank you
