课程大纲
1、讲解如何使用es进行分页搜索的语法
size,from
GET /_search?size=10
GET /_search?size=10&from=0
GET /_search?size=10&from=20
分页的上机实验
GET /test_index/test_type/_search
"hits": {
"total": 9,
"max_score": 1,
我们假设将这9条数据分成3页,每一页是3条数据,来实验一下这个分页搜索的效果
GET /test_index/test_type/_search?from=0&size=3
{
"took": 2,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"hits": {
"total": 9,
"max_score": 1,
"hits": [
{
"_index": "test_index",
"_type": "test_type",
"_id": "8",
"_score": 1,
"_source": {
"test_field": "test client 2"
}
},
{
"_index": "test_index",
"_type": "test_type",
"_id": "6",
"_score": 1,
"_source": {
"test_field": "tes test"
}
},
{
"_index": "test_index",
"_type": "test_type",
"_id": "4",
"_score": 1,
"_source": {
"test_field": "test4"
}
}
]
}
}
第一页:id=8,6,4
GET /test_index/test_type/_search?from=3&size=3
第二页:id=2,自动生成,7
GET /test_index/test_type/_search?from=6&size=3
第三页:id=1,11,3
2、什么是deep paging问题?为什么会产生这个问题,它的底层原理是什么?
deep paging性能问题,以及原理深度图解揭秘,很高级的知识点
