{% include copy-curl.html %}
Now if you run the same query to search for patients older than 75 AND smokers, nothing is returned, which is correct.
You can use the following nested query to search for patients older than 75 OR smokers:
```json
GET testindex1/_search
{
"query": {
"nested": {
"path": "patients",
"query": {
"bool": {
"should": [
{
"term": {
"patients.smoker": true
}
},
{
"range": {
"patients.age": {
"gte": 75
}
}
}
]
}
}
}
}
}
```
{% include copy-curl.html %}
The query correctly returns both patients:
```json
{
"took" : 3,
"took" : 7,
"timed_out" : false,
"_shards" : {
"total" : 1,
"successful" : 1,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : {
"value" : 1,
"relation" : "eq"
},
"max_score" : 0.8465736,
"hits" : [
{
"_index" : "testindex1",
"_id" : "100",
"_score" : 0.8465736,
"_source" : {
"patients" : [
{
"name" : "John Doe",
"age" : 56,
"smoker" : true
},
{
"name" : "Mary Major",
"age" : 85,
"smoker" : false
}
]
}
}
]
}
}
```

The previous query returns no results, as expected:
```json
{
"took" : 7,
"timed_out" : false,
"_shards" : {
"total" : 1,
