1. 创建索引。
创建book索引
put 192.168.0.132:9200/book
{
"settings":{
"number_of_shards":3,
"number_of_replicas": 1
},
"mappings":{
"novel":{
"properties":{
"title":{
"type":"text",
"analyzer": "ik_max_word",
"search_analyzer": "ik_max_word",
"store": false
},
"word_count":{
"type":"integer"
},
"author":{
"type": "text",
"analyzer": "ik_max_word",
"search_analyzer": "ik_max_word",
"store": false
},
"publish_date":{
"type": "date",
"format": "yyyy-MM-dd HH:mm:ss || yyyy-MM-dd||epoch_millis"
}
}
},
"literature":{
}
}
}
number_of_shards 是分片数，
number_of_replicas是备份数。
novel 和 literature 是类型
