Matches the union of its span clauses. The span or query maps to Lucene SpanOrQuery. Here is an example:
{
"span_or" : {
"clauses" : [
{ "span_term" : { "field" : "value1" } },
{ "span_term" : { "field" : "value2" } },
{ "span_term" : { "field" : "value3" } }
]
}
}
The clauses element is a list of one or more other span type queries.
