Hi,
It is up to you to specify which news to index.
Have a look at
<contentDefinition type="news">
<class>com.opencms.modules.homepage.news.NewsContentDefinition</class>
<initClass>net.grcomputing.opencms.search.lucene.NewsInitialization</initCla
ss>
<listMethod name="getNewsList">
<param type="java.lang.Integer">1</param>
<param type="java.lang.String">-1</param>
</listMethod>
<page uri="/news.html?__element=entry">
<param method="getIntId" name="newsid"/>
</page>
</contentDefinition>
The listMethod declares which method should be used to retrieve the news.
The first parameter is the channel id.
You can add another complete contentDefinition section with another channel
id or you can specify another listMethod, for example getSortedList which
takes only one parameter of type String for sorting purpose.
The fix for the null values is not ready, yet, sorry.
Bye,
Stephan
