Searching in nested fields and arrays isn't different from searching in fields on the top level, is it? What have you tried so far?

i'm tried this search:

{
"index":"advertisements",
"type":"anounces",
"body":{
"sort":[{"premium":{"order":"desc"}}],
"query":{
"filtered":{
"filter":{
"bool":{
"should":{
"match":{"coveragearea_without_cities.state.name":"Mimoso do Sul"}
}
}
}
}
}
}
}
