I think, if this must be server side, this could be done in a REST filter plugin, not in the mappings. Matching values against patterns do not relate to field mappings.
Still, the best method to filter out unwanted values is at client side, either at JSON construction time in the official clients, or in the XContentBuilder calls in Java. Reason is to avoid extra load on the data nodes that is not related to index or search. Jörg -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
