GAT has some very powerful filtering right at your fingertips, but you can boost this by an order of magnitude by adding regular expressions to the metadata search criteria.
As one of our customers wisely said if you have a problem that involves having to use a regular expression, then you have two problems….
But good news, we hope to make it a little simpler for you, so here are some regular expressions you might find useful for day to day searching in GAT.
Note in Examples: Domain name = bsn.ie,
ALSO be sure to remember to tick the box ‘Reg Ex’ in the search area

Will catch Test@bsn.ie or firstname.lastname@example.org but not email@example.com

Will catch Nastia@bsn.ie but not Arthur@bsn.ie

Will catch ‘A man called bond X0071234 in a house.’
