"mappings": {
"properties": {
"author":{
"type": "text"
},
"title":{
"type": "text"
},
"paragraphs":{
"analyzer": "ik_max_word",
"type": "text",
"fielddata": "true"
},
"id":{
"type": "text"
}
}
}
}
字段查询
在插入完数据后，进行分词查询
GET song/_search?pretty
{
"size" : 0,
"aggs" : {
"messages" : {
"terms" : {
"size" : 10,
"field" : "paragraphs"
}
}
}
}
查询结果
