Span not query [query-dsl-span-not-query]

Removes matches which overlap with another span query or which are within x tokens before (controlled by the parameter pre) or y tokens after (controlled by the parameter post) another SpanQuery. Here is an example:

GET /_search
{
  "query": {
    "span_not": {
      "include": {
        "span_term": { "field1": "hoya" }
      },
      "exclude": {
        "span_near": {
          "clauses": [
            { "span_term": { "field1": "la" } },
            { "span_term": { "field1": "hoya" } }
          ],
          "slop": 0,
          "in_order": true
        }
      }
    }
  }
}

The include and exclude clauses can be any span type query. The include clause is the span query whose matches are filtered, and the exclude clause is the span query whose matches must not overlap those returned.

In the above example all documents with the term hoya are filtered except the ones that have la preceding them.

Other top level options:

pre : If set the amount of tokens before the include span can’t have overlap with the exclude span. Defaults to 0.

post : If set the amount of tokens after the include span can’t have overlap with the exclude span. Defaults to 0.

dist : If set the amount of tokens from within the include span can’t have overlap with the exclude span. Equivalent of setting both pre and post.
