# reproduced with elasticsearch 1.0.1: 

# index a document with 2 fields, both with the same value (the index will be implicitly generated)

curl -XPOST 'http://localhost:9200/test/test/2' -d '{
    "first_name": "Rochelle",
    "last_name": "Rochelle"
}'

# multi-field terms facet counts the document twice ('count = 2' for the term 'Rochelle')
