 ## Performance
 
-Simple search is not a full-fledged index-powered search engine.  It merely iterates over the pages and searches the content and title for matching strings.  That's it.  This is not going to result in screaming fast searches if your site has lots of content.  One way to optimize things a little is to change the `search_content` configuration option from `rendered` to `raw`.  This means the `rawMarkdown()` method is used rather than the `content()` method, to retrieve the page content, and in turn means plugin events, markdown processing, image processing, and other time consuming tasks are not performed.  This can often yield adequate search results without the need for all this extra work.
