我有相当复杂的 jsonb 列，其中包含嵌套数组和对象。我需要对其进行全文搜索。 json 示例:

实际上我需要搜索 deal_no、buyer.person.phone、buyer.person.address.**。(此处的所有文本值), dealDetails.secondary.sellers[].(此处为所有文本值), bankContacts.(此处为所有文本值)
执行此操作的最佳方法是什么？
我使用postgresql 9.6
最佳答案
这就是我非常相似的任务的样子。
数据库表如下所示:
CREATE TABLE sites (
id text NOT NULL,
doc jsonb,
PRIMARY KEY (id)
)
我们存储在 doc 列中的数据是复杂的嵌套 JSONB 数据:
{
"_id": "123",
"type": "Site",
"identification": "Custom ID",
"title": "SITE 1",
"address": "UK, London, Mr Tom's street, 2",
"buildings": [
{
"uuid": "12312",
"identification": "Custom ID",
"name": "BUILDING 1",
"deposits": [
{
"uuid": "12312",
"identification": "Custom ID",
"audits": [
{
"uuid": "12312",
"sample_id": "SAMPLE ID"
}
]
}
]
}
]
}
所以我的 JSONB 的结构如下所示:
SITE
-> ARRAY OF BUILDINGS
-> ARRAY OF DEPOSITS
-> ARRAY OF AUDITS
我们需要通过每种条目类型中的某些值来实现全文搜索:
SITE (identification, title, address)
BUILDING (identification, name)
DEPOSIT (identification)
AUDIT (sample_id)
SQL 查询应仅在这些字段值中运行全文搜索。
关于postgresql - 对复杂jsonb内容进行全文检索，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/44794073/
