我有一个要求。我正在为社交网络建立搜索服务。搜索服务应返回有人搜索的用户的名称。现在它仅限于用户域搜索。我打算使用弹性搜索来保留索引(用户域详细信息)。然后我将从我的搜索服务中调用EL(搜索服务在nodejs上)。我无法想到如何为EL创建索引的设计。我应该使用批处理来创建索引,还是在创建用户期间我将创建索引。
赞赏一个好的指针或好的设计。

你应该在新用户创建时创建索引
简单的例子可能很有用
您的用户数据如: `
[
{
"_id": "1",
"status": true,
"username": "mak",
"userdomain": "mydomain.com",
"name": "mak doe"
},
{
"_id": "2",
"status": true,
"username": "janny",
"userdomain": "mydomain.com",
"name": "janny"
},
{
"_id": "3",
"status": true,
"username": "mac",
"userdomain": "newdomain.com",
"name": "mac peter"
},
{
"_id": "4",
"status": true,
"username": "mak",
"userdomain": "mydomain.com",
"name": "mak peter"
},
{
"id": "5",
"status": true,
"username": "mak",
"userdomain": "newdomain.com",
"name": "mak peter"
},
]
`
弹性模式如下所示: `
PUT socialdata
{
"mappings": {
"users": {
"properties": {
"status": {
"type": "boolean"
},
"name": {
"type": "text"
},
"username": {
"type": "string",
"fields": {
"raw": {
"type": "string",
"analyzer": "keyword_lowercase_analyzer"
},
"english": {
"type": "text",
"analyzer": "english"
}
}
},
"userdomain": {
"type": "string",
"fields": {
"raw": {
"type": "string",
"analyzer": "keyword_lowercase_analyzer"
},
"english": {
"type": "text",
"analyzer": "english"
}
}
}
}
}
}
}
`
批量上传: `
POST socialdata/users/_bulk
{ "index": { "_index": "socialdata","_type": "users", "_id": 1 }}
{"status":true,"username": "mak","userdomain": "mydomain.com","name": "mak doe"}
{ "index": { "_index": "socialdata","_type": "users", "_id": 2 }}
{"status":true,"username": "janny","userdomain": "mydomain.com","name": "janny"}
{ "index": { "_index": "socialdata","_type": "users", "_id": 3 }}
{"status":true,"username": "mac","userdomain": "newdomain.com","name": "mac peter"}
{ "index": { "_index": "socialdata","_type": "users", "_id": 4 }}
{"status":true,"username": "mak","userdomain": "mydomain.com","name": "mak peter"}
{ "index": { "_index": "socialdata","_type": "users", "_id": 5 }}
{"status":true,"username": "mak","userdomain": "newdomain.com","name": "mak peter"}
`
单个索引的: `
POST socialdata/users/_bulk
{ "index": { "_index": "socialdata","_type": "users", "_id": 1 }}
{"status":true,"username": "mak","userdomain": "mydomain.com","name": "mak doe"}
`
弹性查询: 它只会返回两个记录 `
POST socialdata/users/_search
{
"query": {
"bool": {
"must": [
{
"match": {
"username": "mak"
}
},
{
"match": {
"userdomain": "mydomain.com"
}
}
]
}
}
}
`
它只会返回一条记录 `
POST socialdata/users/_search
{
"query": {
"bool": {
"must": [
{
"match": {
"username": "mak"
}
},
{
"match": {
"userdomain": "newdomain.com"
}
}
]
}
}
}
`
