How can i change the design for the search results?

It seems the output page has its own way of displaying the articles and does not use the catergory settings at all.

Since K2 is already full of options i really wish that i could easily edit how the search results will be displayed (pretty much like the category settings). Is there an easy way without doing templates/php/css?

Hi. It depends what kind of search you mean. Are you using Joomla! search (mod_search) or K2 search (mod_k2_tools)? If you are using K2 search then there are some options for this under "Layout & view options for Search & Date listings" section in K2 parameters. If what you want to do is not covered by these options, then you need to make a template override.
