I don't think you actually want the data to end up in entirely different indexes. Although it is possible to search more than one separate index, that's very likely NOT what you want to do, and it comes with its own challenges. What you most likely want is to put this data into different fields within the same index. You'll need to write custom code to accomplish this, especially if you need the stored data to contain only the parts rather than the complete email address. A copyField can get the data to additional fields, but I'm not aware of anything built-in to the schema that can trim the unwanted information from the new fields, and even if there is, any stored data will be the original data for all three fields. It's up to you whether this custom code is in a user application that does your indexing or in a custom update processor that you load as a plugin to Solr itself. Extending whatever user application you are already using for indexing is very likely to be a lot easier. Thanks, Shawn
