Java高级教程之ElasticSearch-5：ElasticSearch批量记录增加和查询
批量添加记录的接口为_bulk，需要文件account.json，使用参数--data-binary发送二进制文件数据:
curl -H "Content-Type: application/json" -XPOST "localhost:9200/bank/_bulk?pretty&refresh" --data-binary "@accounts.json"
文件：
account.json
发送请求后，自动创建了bank的索引。返回结果中took即是使用了多长时间，其他参数是创建成功的记录数据，包括_id，result等。
{
"took" : 16173,
"errors" : false,
"items" : [
{
"index" : {
"_index" : "bank",
"_type" : "_doc",
"_id" : "1",
"_version" : 1,
"result" : "created",
"forced_refresh" : true,
"_shards" : {
"total" : 2,
"successful" : 2,
"failed" : 0
},
"_seq_no" : 0,
"_primary_term" : 1,
"status" : 201
}
},
{
"index" : {
"_index" : "bank",
"_type" : "_doc",
"_id" : "6",
"_version" : 1,
"result" : "created",
"forced_refresh" : true,
"_shards" : {
"total" : 2,
"successful" : 2,
"failed" : 0
},
"_seq_no" : 1,
"_primary_term" : 1,
"status" : 201
}
},
{
"index" : {
"_index" : "bank",
"_type" : "_doc",
"_id" : "13",
"_version" : 1,
"result" : "created",
"forced_refresh" : true,
"_shards" : {
"total" : 2,
"successful" : 2,
"failed" : 0
},
"_seq_no" : 2,
"_primary_term" : 1,
"status" : 201
}
},
{
"index" : {
"_index" : "bank",
"_type" : "_doc",
"_id" : "18",
"_version" : 1,
"result" : "created",
"forced_refresh" : true,
"_shards" : {
"total" : 2,
"successful" : 2,
"failed" : 0
},
"_seq_no" : 3,
"_primary_term" : 1,
"status" : 201
}
},
{
"index" : {
"_index" : "bank",
"_type" : "_doc",
"_id" : "20",
"_version" : 1,
"result" : "created",
"forced_refresh" : true,
"_shards" : {
"total" : 2,
"successful" : 2,
"failed" : 0
},
"_seq_no" : 4,
"_primary_term" : 1,
"status" : 201
}
},
{
"index" : {
"_index" : "bank",
"_type" : "_doc",
"_id" : "25",
"_version" : 1,
"result" : "created",
"forced_refresh" : true,
"_shards" : {
"total" : 2,
"successful" : 2,
"failed" : 0
},
"_seq_no" : 5,
"_primary_term" : 1,
"status" : 201
}
},
....
现在使用_search进行查询：
curl -X GET "localhost:9200/bank/_search?pretty" -H 'Content-Type: application/json' -d'
{
"query": { "match_all": {} },
"sort": [
{ "account_number": "asc" }
]
}
'
查询语句中加入了query和sort两个字段。查询的是match_all，排序以字段account_number降序。
这种请求体是ElasticSearch的特定规则。实际上是查询所有记录，但默认只返回前10条。
请求结果：
{
"took" : 2733,
"timed_out" : false,
"_shards" : {
"total" : 1,
"successful" : 1,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : {
"value" : 1000,
"relation" : "eq"
},
"max_score" : null,
"hits" : [
