Odoo dbfilter allow many options like website-domain based odoo dbfilter, fixed domain filter, any database selection filter, etc…

In case we had database like awsmanager.snippetbucket.com, test.snippetbucket.com, snippetbucket.com

dbfilter = ^(test.snippetbucket.com|snippetbucket.com)$

Out of many database, it will pick only two database, similar modification can be done as needed.
