XPATH

 A search on Google does not return too many insightful results. One implementation of XPATH against Lucene can be found in the CMS [http://wiki.alfresco.com/wiki/Search_Documentation Alfresco], albeit with severe limitations: "does not currently support the attribute axis or predictes".
 
-A hint as to their implementation is the [http://wiki.alfresco.com/wiki/Search_Documentation#Lucene_Language description of Alfresco's Lucene index].
+A hint as to their implementation is the [http://wiki.alfresco.com/wiki/Search_Documentation#Lucene_Language description of Alfresco's Lucene index]. It appears as if they use a dedicated field in the index to operate on with XPATH :
+ {{{
+#  PATH
+
+    * An XPATH expression used to select nodes
+    * This should only be access via a phrase query (ie in "") as it requires special tokenisation
+ }}}
+I'm currently looking into their sources to learn more about their implementation, specificaly [http://dev.alfresco.com/resource/docs/java/repository/org/alfresco/util/SearchLanguageConversion.html org.alfresco.util.SearchLanguageConversion].
