MediaWiki features

Hi, I am new to XWiki and I cannot find some features which I know from MediaWiki. Please, can you give me a hint whether these features exist in XWiki? 1) How can I _directly_ jump to a page which name I know? If I enter a pagename into the search field, a full text search is done and I get a lot of hits. 2) Are umlauts (e. g. "ä", which is ä) in pagenames possible? 3) Can I have redirects to another page (not URLs)? Like #REDIRECT [[pagename]] in MediaWiki. 4) How do categories work? Like [[Category:catname]] in MediaWiki. 5) Can I edit just paragraphs/chapters of a page, instead of the whole page? Like in MediaWiki ... ;-) 6) Is there a preview function to check the layout of a page before saving it?
