我有以下架构
collectionName:{
name:string,
address:string,
info:["info1","info2",....."infon"] // this is array of strings
}
我在mongodb Atlas中创建了搜索索引如下
{
"mappings": {
"dynamic": false,
"fields": {
"name": [
{
"multi": {
"simpleAnalyzer": {
"analyzer": "lucene.simple",
"type": "string"
}
},
"type": "string"
}
],
"address": [
{
"multi": {
"simpleAnalyzer": {
"analyzer": "lucene.simple",
"type": "string"
}
},
"type": "string"
}
],
"info": [
{
"type": "string"
}
]
}
}
}
以下查询适用于 address 和 name ,但不适用于 info 。
db.collectionName.aggregate([
{
$search: {
index:'txtIdx', //this is my index name
text: {
query: "info1",
path: "info",
// path:['name','address','info'],
fuzzy: {
maxEdits: 2,
prefixLength: 3,
},
},
},
},
{
$project: {
_id: 0,
name: 1,
address:1,
info:1,
score: { $meta: "searchScore" }
}
},
{$limit:100},
{
$sort:{
score:-1
}
}
])
我什至尝试为 info 字段创建索引,如下所示
"info":{
{
"type": "document"
},
{
"type": "string"
}
}
但即使字符串存在于信息数组中,它仍然给出空结果 有人能告诉我我哪里出错了吗?此外,我只想使用文本搜索索引方式来执行此操作...所以请告诉我如何解决此问题?
