Returns matches which are enclosed inside another span query. The span within
query maps to Lucene SpanWithinQuery. Here is an example:
GET /_search
{
"query": {
"span_within" : {
"little" : {
"span_term" : { "field1" : "foo" }
},
"big" : {
"span_near" : {
"clauses" : [
{ "span_term" : { "field1" : "bar" } },
{ "span_term" : { "field1" : "baz" } }
],
"slop" : 5,
"in_order" : true
}
}
}
}
}The big and little clauses can be any span type query. Matching
spans from little that are enclosed within big are returned.
