Hi! Depending on the purpose you could use the custom aud-columns like this:

You could override AuditStrategy#addEntityAtRevisionRestriction and add a where-clause to the root-parameters.
queryBuilder.getRootParameters().addWhereWithParam("foo", "<>", "bar");

Or for a custom column "foo" you implement FooPropertyNameGetter and query like this:
AuditReaderFactory.get(em).createQuery().forRevisionsOfEntity(..).add(new SimpleAuditExpression(null, new FooPropertyNameGetter(), "bar", "=")).getResultList();

Or you use external native queries.
