[xwiki-users] Setting view deny permission on specific page?

Hi All, I want to set the view deny permission on specific page for group XWikiAllGroup through groovy script. This is my groovy script i tried Document docSetSearchableRights=xwiki.getDocument("Xwiki.User1") if(docSetSearchableRights!=null) { com.xpn.xwiki.api.Object rightsToSearchObject=docSetSearchableRights.newObject("XWiki.XWikiRights") rightsToSearchObject.set("groups", "XWiki.XWikiAllGroup") rightsToSearchObject.set("levels", "view") rightsToSearchObject.set("allow", "0") // also tried value 2 but does not work. docSetSearchableRights.save() } Above i am trying to set view deny permission to group XWiki.XWikiAllGroup on page Xwiki.User1. But when i go access rights section of User1 page, i do not see deny permission set on view for group XWikiAllGroup. For information, The reason i am doing it is i do not want user profiles visible in serach results. i was able to do it from xwiki ui by edit the access rights of that page and deny the view permission of that user profile page to XWikiAllGoup . But in the question, i am trying to do it from groovy script.
