Term

• Frequently used to match on exact value
• Equivalent of sql statement:

  select * from orders where id = "1"
  

• Example

  curl 'localhost:9200/ordering/orders/_search?pretty=true' -d '{
  "query" : {
    "term": {
      "id": "1"
    }
  }
  }'
  

• Note that 'from orders' part of the statement is part of the url rather than body
• Capable of handling numbers, booleans, dates, and text.
• Often used as a filter rather than for scoring, commonly used with 'constant_score':

  curl 'localhost:9200/ordering/orders/_search?pretty=true' -d '{
  "query" : {
    "constant_score" : { 
      "filter" : {
        "term": {
          "id": "1"
        }
      }
    }
  }
  }'
