Span term query [query-dsl-span-term-query]

Matches spans containing a term. Here is an example:

GET /_search
{
  "query": {
    "span_term" : { "user.id" : "kimchy" }
  }
}

A boost can also be associated with the query:

GET /_search
{
  "query": {
    "span_term" : { "user.id" : { "value" : "kimchy", "boost" : 2.0 } }
  }
}

Or :

GET /_search
{
  "query": {
    "span_term" : { "user.id" : { "term" : "kimchy", "boost" : 2.0 } }
  }
}
