# 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:
|
|||
|
|
|
|||
|
|
```console
|
|||
|
|
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`.
