-   CSS-highlights the terms used as search patterns. This is done
-   by evaluating the REFERRER and using the QUERY_STRINGs "q="
-   parameter (which is used by Google and ewikis` PowerSearch).
-
-   Using this plugin costs you nearly nothing (not slower), because
-   there most often isn't a "?q=" from a search engine in the referer
-   url.

-   Modified 20040811 by Jochen Schuh
-     
-   Missing feature:
-     Different search words are now marked different so they could 
-     (but must not) styled individually.
-     
-   CSS styling examples:
-   - I prefer to highlight only in the contents of the page, not in the
-     menu or the list of modules or the footer. This is done with:
-          em {
-            font-style:normal;
-          }
-   - To style all of the searchwords the same you can use this rule. Using
-     only this rule would be enough to style all searchwords. But also if
-     you want to style individually such a styling rule is heavily
-     recommended as fallback to style a possible 10. or 42. searchword:
-          .text-body em.highlight {
-            border-top: solid;
-            border-bottom: solid;
-            border-width: 1px;
-            padding-top: 1px;
-            padding-bottom: 1px;
-            border-color: #000000;
-            background-color: #EEEEEE;
-          }
-   - The first few searchwords _can_ easily styled different with:
-          .text-body em.searchword-0 {
-            border-color: #0066FF;
-            background-color: #E8F4FF;
-          }
-          .text-body em.searchword-1 {
-            border-color: #FF6600;
-            background-color: #FFF4E8;
-          }
