Elastic Search Street Range Search

问题

We have two fields Street Number 1 & Street Number 2 in Elastic Search. We also have an Address field in Elastic Search and Address is a combination of 2 fields with some other fields. So we have an address as:

• 1604-1612 Calver Building
• 1608- 1645 Park House

If the user is searching with 1610 both the address should be returned.

Any help on how the query can be formed?

The idea would be to leverage the range data type and store the min and max street number in that field.

In your mapping, you'd have something like this:

PUT property_index
{
  "mappings": {
    "_doc": {
      "properties": {
        "street_number_range": {
          "type": "integer_range"
        },
        "street_name": {
          "type": "text"
        }
      }
    }
  }
}

Then you can add your two documents like this:

PUT property_index/_doc/1
{
  "street_number_range" : { 
    "gte" : 1604,
    "lte" : 1612
  },
  "street_name": "Calver Building"
}

PUT property_index/_doc/2
{
  "street_number_range" : { 
    "gte" : 1608,
    "lte" : 1645
  },
  "street_name": "Park House"
}

Finally, your query would look like this and wold return both documents

GET property_index/_search
{
  "query" : {
    "term" : {
      "street_number_range" : {
        "value": 1610
      }
    }
  }
}

UPDATE

You can also search for a range with the following query:

GET property_index/_search
{
  "query" : {
    "range" : {
      "street_number_range" : {
        "gte": 1600,
        "lte": 1650
      }
    }
  }
}
