How to create Percolate index in Elasticsearch on multiple fields?

Question

elasticsearch

There is a product index

curl -XPUT "http://localhost:9200/products/product/1" -d'
{
    "title": "Iphone 6",
    "category_id": 4,
    "price": 7788,
    "owner_id": 21
}'

How to create a percolate index on 3 fields: title, category_id, price?
Percolate Query has an example here but only for 1 field.
