Alfresco 2.1 Opensearch with ie7

[skorde]

Hi
I have  Alfresco 2.1 server
I'm trying to add other search engines(like described in the wiki)
I've put the following code in the web-scripts-config-custom

<engine label="Alfresco Open Source Talk" proxy="opentalk">
               <url type="application/rss+xml">
                  http://blogs.alfresco.com/opentalk/os-query?s={searchTerms}&itemstart={startIndex?}&itempage={startP...?}
               </url>
            </engine>
          <engine label="Yahoo UK News" proxy="yahooUKNews">
               <url type="application/rss+xml">
                  http://uk.news.search.yahoo.com/news/rss?p={searchTerms}
               </url>
            </engine>

            <engine label="Yahoo Search" proxy="yahoo">
               <url type="application/rss+xml">
                  http://api.search.yahoo.com/WebSearchService/rss/webSearch.xml?appid=yahoosearchwebrss&query={search...?}
               </url>
            </engine>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
