Rida, There is something I would like to clarify, when using a namespace and xpath to store content in the index, can this be seen as multi-fields. For example if we are storing customer name and customer address which are been declared in a xml configuration file, is that multi-field. Please explain, sorry I am quite new to the Nutch architecture.
