A query that applies a filter to the results of another query. This query maps to Lucene FilteredQuery.
{
"filtered" : {
"query" : {
"term" : { "tag" : "wow" }
},
"filter" : {
"range" : {
"age" : { "from" : 10, "to" : 20 }
}
}
}
}
The filter object can hold only filter elements, not queries. Filters can be much faster compared to queries since they don’t perform any scoring, especially when they are cached.
