Can't delete documents, how to do it?

I’ve tried index deletion but it doesn’t seem to work. It took half a day to to a simulation delete and then delete but i still have the same amount of documents.
Here are the steps I’ve done:
-click on “index administration” --> then “index deletion” tab.
-on “Delete by URL Matching” type for example,
-click on “simulate deletion” And wait, wait, wait (took half a day)
-then I can finally click on “engage deletion” button, and wait, wait some more.
Then I get that x amount of documents are deleted. which seems wrong 'cause my total amount of documents has not changed.
-restart yacy a day later and nothing seems changed.

Thanks for any help.

I’m having this same problem.

I just tried that without problems. How large is the index?
