+ 
+ As of Jackrabbit 1.6 you can define includes on a property level. Properties that match the path against the root of an indexing aggregate are included in the aggregated node index. Aggregated properties are also used to speed up sorting of query results when the order by clause references a property with a relative path. Please make sure you use the correct DTD (the 1.2 version):
+ 
+ {{{

+ <!DOCTYPE configuration SYSTEM "http://jackrabbit.apache.org/dtd/indexing-configuration-1.2.dtd">
+ <configuration xmlns:jcr="http://www.jcp.org/jcr/1.0"
+                xmlns:nt="http://www.jcp.org/jcr/nt/1.0">
+   <aggregate primaryType="nt:file">
+     <include>jcr:content</include>
+     <include-property>jcr:content/jcr:lastModified</include-property>
+   </aggregate>
+ </configuration>
