I've been experimenting with percolator, but it seems I can't add queries for fields that have no mappings. This would be really useful for me. I was wondering if it would be possible to use copy_to to in a dynamic template to copy the path AND the value for any string fields. For an example, I could have a known mapped nested type field that contains 2 properties: path and value. Then I could dynamically copy string field values into the value property, and the path that the string field was found in to the path property.
Is there anyway for me to write a percolator query for a field that the index has no mapping for even though we dynamically map these?
