Open Kibana and load the mappings and queries below into the dev tools.

Add the mapping abc-product

DELETE /abc-product

GET /abc-product/

#
# Create The Mapping
#
PUT /abc-product
{
  "mappings": {
    "properties": {
      "product_name": {
        "type": "search_as_you_type"
      },
      "category_search": {
        "type": "search_as_you_type"
      },
      "category": {
        "type": "keyword"
      },
      "price": {
        "type": "float"
      },
      "description": {
        "type": "text"
      }
    }
  }
}

Edit the abcycling-logstash.conf to point at your elasticsearch and run logstash

sudo /home/install/7.5.1/logstash-7.5.1/bin/logstash -r -f ./abcycling-logstash.conf

Then we will try some search-as-you-type samples
