search should display surrounding contents

search results do not show any context and contents of the page why the this entry is in the search result.

mediawiki search is an example for good looking, and efficient:

• "find-me" brings up the page, if a title exactly like this exists
  otherwise fulltext search
• "find-me*" brings up the page, if a title nearly like this exists
  otherwise fulltext search
• "find-me" does in all cases a fulltext-search
• result of fulltext search displays parts of content marked
  in red so you know immediately if clicking on one of the results
  will help you.
