In my wiki, I can search for topics but the content ist not displayed. I only can see my text in the edit mode.
Does anyone has an idea what the problem could be?

By "can see my text in the edit mode", do you mean to say the content part in the search results shows up in Wikitext, such as showing square brackets for links etc?
If so, I think this is the default behaviour. To obtain results in the form of Wikimedia Foundation Wikis you will have to install Extension:CirrusSearch.
