Humm... there is something I dont catch..
When you open up an index writer, you batch up add and deletes. Now if
you create a signature for the document, as long as you add it works,
but what happens if you delete stuff from the index using a query as
well as adding?
Does Solr also remember the deletions as well?

not at all ... it computes a signature and then uses that as a unique key.
IndexWriter.updateDocument does all the hard work.
Right - Solr used to do that hard work, but we handed that over to
Lucene when that capability was added. It involves batching either
way (but letting Lucene handle it at a lower level is "better" since
it can prevent inconsistencies from crashes).
