More-Complicated Searchesedit
Let’s make the search a little more complicated. We still want to find all employees with a last name of Smith, but we want only employees who are older than 30. Our query will change a little to accommodate a filter, which allows us to execute structured searches efficiently:
GET /megacorp/employee/_search
{
"query" : {
"bool" : {
"must" : {
"match" : {
"last_name" : "smith"
}
},
"filter" : {
"range" : {
"age" : { "gt" : 30 }
}
}
}
}
}

This portion of the query is the same |

This portion of the query is a |
Don’t worry about the syntax too much for now; we will cover it in great
detail later. Just recognize that we’ve added a filter that performs a
range search, and reused the same match query as before. Now our results show
only one employee who happens to be 32 and is named Jane Smith:

"hits": {
"total": 1,
"max_score": 0.30685282,
"hits": [

...
"_source": {
"first_name": "Jane",
"last_name": "Smith",
"age": 32,
"about": "I like to collect rock albums",
"interests": [ "music" ]
}
}
]
}
}
